If the cycle develops net work at a rate of 85.5 kJ per kg of carbon dioxide flowing through the turbine, determine the thermal efficiency, back work ratio, isentropic efficiency of each compressor stage, and isentropic turbine efficiency.

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

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
