An ideal diesel cycle has a maximum cycle temperature of 2300°f and a cutoff ratio of 1.4. the state of the air at the beginning of the compression is p1=14.4 psia and t1=50°f. this cycle is executed in a four- stroke, eight-cylinder engine with a cylinder bore of 4 in and a piston stroke of 4 in. the minimum volume enclosed in the cylinder is 4.5 percent of the maximum cylinder volume. determine the power produced by this engine when it is operated at 1800 rpm. use constant specific heats at room temperature. (unit is hp)

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
