Q14:- The turning moment diagram for a four stroke gas engine may be represented by four triangles, the area of which from the line of zero pressure are as follows:- expansion stroke =35.5 cm', exhaust stroke = 5 cm, suction stroke =3.5 cm? and the compression stroke =14 cm, each cm? represents 30 N.m. Assuming the resisting moment to be uniform, find the weight of the rim of the flywheel required to keep the mean speed 200 rpm within ±2%. The mean radius of the rim may be taken as 75 cm. Also determine the crank positions for the maximum and minimum speeds.

It is the ability of a liquid to spread out.
Suppose a hippopotamus on land receives 73 units of heat per minute due to solar radiation and 52 units of heat per minute due to infrared radiation. It emits 39 units of infrared radiation and it loses 66 units heat per minute through evaporation. The hippopotamus gains 45 units of heat per minute through its metabolism. Overall, its heat energy is increasing by 50 units per minute (i.e. its temperature is increasing). Delta Hanimal = SR + IRin - IRout ± Hconv ± Hcond - Hevap + Hmet Based on this information we can conclude that the combination of conduction and convection is the animal, and that its current temperature is than the ambient temperature. Select one: a. cooling; warmer b. warming; warmer c. cooling; cooler d. warming; cooler

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
There may or may not be one or more mistakes in the solution. Go through the solution carefully and then do the following. 1. State if the solution is correct or incorrect 2. If the solution is incorrect, identify what is the mistake in the solution. Be specific and succinct. 3. If the solution is incorrect, provide the final solution with appropriate steps. Problem: A refrigeration cycle uses refrigerant R-134a to cool down water from 40°C to 20°C. The refrigerant R-134a enters the cycle as saturated liquid at -15°C and exits as saturated vapor at the same temperature. The mass flow rate of R-134a is 0.12 kg/s. The overall heat transfer coefficient is 1400 W/m².K. The surface area of the heat exchanger is 1.4 m². What is the rate at which heat is being exchanged between R-134a and water? Assume that the heat exchanger is perfectly insulated from outside (i.e., there is no convection or radiation with the outside/surrounding). Solution: We know, from the definition of overall heat…
