In an ideal rankine cycle, superheated vapor enters the turbine at 200 bar and 600℃, and the condenser pressure is 0.1 bar. the mass flow rate of the steam entering the turbine is 110 kg/s. determine (a) the thermal efficiency, (b) the mass flow rate of condenser cooling water, in kg/s, if the cooling water undergoes a temperature increase of 18k with negligible pressure change in passing through the condenser and boiler.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Determine the damped natural frequencies and the steady state response of a decoupled damped forced two degrees of freedom system. 10ä1 + 2q1 20q1 10 cos t; 10q2 +4q2 + 40q2 10 cos t

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
