Athree-cylinder engine has the cranks spaced at equal angular intervals of 120 each crank is 140 mm long and each connecting rod is 615 mm long. the pitch of the cylinders is 420 mm and the speed is 550 rev/min. if the reciprocating parts per cylinder have a mass of 70 kg, find the maximum unbalanced primary and secondary effects of the reciprocating parts.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
