The conditionsat the beginning of compression are 37 oC, 98 kPaa, and 3.7 liters. If the engine operatesat 1500 rpm, determine a) the compression ratio; b) the cycle work; and c) the powereddeveloped.
An ideal Otto cycle has a compression ratio of 10.5, takes in air at 90 kPa and 40°C, and is repeated 2500 times per minute. The Thermal efficiency is 60.96% and the Rate of Heat Input of 147.6409 kW if the cycle is to produce 90 kW of power. Draw and label the P-V and T-S diagrams.
In an ideal Rankine cycle, the steam throttle condition is 4.10 MPa and 440oC. If turbine exhaust is 0.105 MPa, determine the thermal efficiency of the cycle.

An ideal Diesel cycle has a maximum cycle tempera¬ture of 2000°C. The state of the air at the beginning of the compression is P1 = 90 kPa and T1 = 15°C. This cycle is exe¬cuted in a four-stroke, eight-cylinder engine with a cylinder bore of 12 cm and a piston stroke of 14 cm. The minimum volume enclosed in the cylinder is 5 percent of the maximum cylinder volume. Determine the power produced by this engine when it is operated at 1500 rpm. Use constant specific heats at room temperature.
