Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero

At flow nozzle is to be installedin a 5-in type k copper tube carrying linseed oil at 77 f. a mercury manometer is to be used to measure the pressure difference across the nozzle when the expected range of the flow rate is from 700 galmin to 1000 gal/min. the manometer scale ranges from 0 to 8.0 in of mercury determine an appropriate diameter of the nozzle.

An ideal vapour-compression heat pump cycle provides a heating rate of 12btu/s. the working fluid, refrigerant 134a, enters the compressor as a saturated vapor at 40 psi and exits the condenser as a saturated liquid at 160 psi. determine (a) the mass flow rate of the working fluid in lb/min (b) the compressor power in btu/min. (c) the coefficient of performance.
