The curve of the power torque graph for the polo engine slopes smoothly and increases steadily as the revolutions per minute increase. The relationship of torque versus the engine is non linear. This relationship is provided as curve as shown on the torque curve. The exact shape and the height of the curve is specific for each engine type and this is normally determined by engine tests. The curve peaks at approximately 4000 rpm with a torque of about 90.3 N/M. The curves can be defined within the range of 1100-5500 rpm since that is the operating range of the polo engine. If the range is made lower than this, the engine is likely to stall while an increase would damage the engine.
For energy balance to occur within the internal combustion engine, it is important that the total power generated by the brake power is kept at its peak. Energy performance is an indication of the degree at which the success of the internal combustion polo engine performs its assigned task. The total power is normally developed by the combustion of the fuel in the combustion chamber is greater than the brake power usually referred to as indicated power. This can be calculated as:
The balance of the energy in the internal combustion engine will indicate that approximately 1/3 of the fuel energy that has been input is normally lost to the external environment through transfer of heat. There is also another 1/3 is available as the shaft performs its work. The heat losses must be decreased in order to improve the efficiency of the engine.
3. Exhaust smoke and other emissions: The oxides of nitrogen and any unburned carbons are an indication of the rate of efficiency of the engine. This parameter can be used ...Download file to see next pagesRead More

... Introduction. Specific gravity can be regarded as the ratio between the mass of volume of a given soil particle to the mass ofa similar distilled water volume for a temperature. This can be represented mathematically, using equation1. = , ....................................................................................................1 with being the specific gravity at a dimension of four degrees, being the solid’s mass density, with as water’s mass density. Considering this, four degrees temperature served as the reference temperature identified scientifically basic on the fact that it corresponds to the highest water density. More often than not, when dealing with mechanics of soil, twenty degrees Celsius serves as the best...

Three are family members and one is a significant other. Before asking them to participate in the experiment, I decided to warm them up with friendly conversation. Then, I asked them to participate, they were informed of the requirements, and I had them sign the informed consent forms. They completely understood the instructions, so there was no need to go into deep detail regarding the experiment. They were also friendly and eager to participate. They supported studies such as the one we were undertaking... in this...

For the Number of hours watching television—“tvhours” variable, run the appropriate statistics and visual representation and assess the distribution. ( 2 marks) a) Briefly interpret the results for the “tvhours” variable. Are people watching a lot of TV? The average number of hours per day that respondents (whole population) watch television is about 2.9 hours (SD = 2.24). About half of the respondents watch television up to 2 hours per day. About 50% of the respondents watch television in between 2 to 4 hours per day. Most of the respondents watch television 2 hours per day... OF...

...I confirm that I have not received help from, or given help to, anyone else in constructing the solution to this assignment. here and signature above) No. 530542 Problem: A block of mass m g is released at a distance h m above one end of a certain vertical non-linear spring. The other end of the spring is fixed. 1. Given the constants k1, k2, a and b, we can solve for the force F(x) in the compressed spring using the equation F(x) = k1xa + k2xb. Question 1 requires a plot of the variation of force F(x) for values of x from 0 to 6h using MATLAB. The constants k1, k2, h, a and b can be computed using our student number: k1 = 45000 (1 + 5) = 270000 k2 = 45000 (1 + 0) = 8100 a = 1 + 0.01(0) = 1 b = 1.5 + 0.01(5... confirm that...

... Procedure This experiment requires three cuvettes, a spectrophotometer, a graduated cylinder, dye of three differentcolours. The first step is to fill the three cuvettes with red dye, green dye and blue dye with each holding a dye of different colour. The initial concentrations of these dye is 100% at the beginning of the experiment. The cuvettes are then placed into a spectrophotometer. They are oriented in such a way that their smooth sides lining face the light source to enable easy penetration of light through them. Multiple trials were then performed because the spectrophotometer can only measure one sample at a time. In order to ensure accuracy and precision, it was necessary to re-calibrate the spectrophotometer three... Procedure...

Discuss the resources which were most significant to them. The majority of the origins of people in Michigan are Native American; which arrived between 12,000 and 14,000 years ago. These Paleo-Indian peoples traveled from Alaska and Asia across the Bering Straits. The most important resources to these peoples were the herds of caribou, mastodons, and mammoths; they relied upon these animals for food and furs for clothing.

...Experiment #3 — observing the Moon’s Phases Objective To determine the relationship of the Earth, Moon and Sun as the Moon orbits the Earth. Introduction In astronomy, determining the relative position of the moon, the sun and the Earth requires the study of phases of the moon at different days of observation. In which case, complete cycle through the phases called lunar month gives the synodic month, always around 29 days. The lab report studied these phenomena to realize moon’s position in relation to the other two. Procedure The moon was observed and a dark part was shaded to show how the moon would look like at each point from the Earth. Each phases of the moon was labeled and presented in diagram forms as shown in...

...Lab It is crucial to familiarize with various concepts before conducting lab experiments. One of the importantconcepts for this experiment is solubility, which can be defined as the ability of a substance (solute) to dissolve in another (solvent) (Bauer et al. 216). The estimation maximum quantity of a substance that dissolves in a solvent at equilibrium yields solubility (Brown et al. 120). Qualitative analysis is done to identify elements in the sample used for the experiment. For this experiment, qualitative analysis was employed to establish whether or not a precipitate would form upon adding some acids and bases. A flow chart was used to distinguish between cations in the resultant solution. A flow...

Calorimeter also known as spectrometer is a tool that is used in figuring out the quantity of light that a given solution absorbs while using various wavelengths (λ).The spectrometer cannot determine the quantity of light absorbed(A) by certain solution unless calibration is done first. The opposite of Transmittance (T %) is Absorbance (A) which can be defined as the quantity of light that is absorbed or transmitted through a sample. Moreover, a highly concentrated solution is, the more it absorbs light, and the less transmitted light...
