Q2: A spark ignition engine has a swept volume of 2.0 liters, and operates on the four-stroke cycle. When installed in the Rover vehicle, the operating point for a vehicle speed of 120 kmh corresponds to 3669 pm, and a torque of 71.85 N.m, for which the specific fuel consumption in 298 gkWh. Calculate the bmep at this operating point, the arbitrary ovenall efficiency and the fuel economy (liters/100km). If the air fuel ratio is 20:1, calculate the valumetric efficiency of the engine. The calorific (heating) value of the fuel is 43 MIky, and its density is 795 kg/m'. Ambient conditines are 27 "C and L05 har.

Suppose that in some location, thermal solar electricity can be produced at a cost of 4¢ per kilowatt hour (kWh), while electricity from coal costs 3.5¢ per kWh (note that thermal solar can be stored up and released overnight, so you can assume that there are no problems with intermittency). Suppose there is enough coal to last 100 more years at current use levels, and suppose for now that virtually all of the cost of making electricity from coal is the coal itself.7 If the real rate of interest is 2%, what do you expect to happen to the current price of coal?

A pump delivers gasoline ( = 685.75 kg/m3) at 20°C and 13.65 m3/h. At the inlet, P1 = 112.5 kPa, z1 = 1.25 m and V1 = 2.75 m/s. At the output, P2 = 555 kPa, z2 = 5 m and V2 = 3.375 m/s. How much power is required if the motor efficiency is 77.5%?
The figure below shows a turbine-driven pump that provides water to a mixing chamber located dz⁢= 5 m higher than the pump, where m˙=50 kg/s. Steady-state operating data for the turbine and pump are labeled on the figure. Heat transfer from the water to its surroundings occurs at a rate of 2 kW. For the turbine, heat transfer with the surroundings and potential energy effects are negligible. Kinetic energy effects at all numbered states can be ignored. Determine:(a) the magnitude of the pump power, in kW.(b) the mass flow rate of steam, in kg/s, that flows through the turbine.
