The displacement volume of an internal combustion engine is 3 liters. the cycle can be modeled as an ideal diesel cycle with a cutoff ratio of 2.5. the state of the air at the beginning of compression is 95kpa, 22°c with a volume of 3.17 liters. determine the net work per cycle, in kj, and the power developed by the engine, in kw, if the cycle is executed 1000 times per minute.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
