A 4cylinder racing engine capacity 2.495liters has a bore of 94mm and a compression ration 12/1 when tested against a dynamometer with a torque arm of 0.461m. A maximum load of 622N was obtained at 5000rpm, and at the peak speed of 6750 rpm, thebload was 547N the minimum fiel consumption was 17.2mililitre/s at a speed of 5000rpm. the specific gravity of the fuel bieng 0.735 and Cv=44200Kj/kg. calvulate the maximum Brake mean effective pressure

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

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

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
