Apump supplies 2kg/s of water at 20 bar and 40°c to a boiler. the boiler adds heat at a rate of 5713kw to the water (you may assume that this is a constant pressure process). steam from the boiler passes through a steam turbine and exits at 10kpa, 60°c. (i) calculate the enthalpy rise of the water as it passes through the boiler. (ii) determine the approximate temperature of the steam as it leaves the boiler. (iii) what state is the steam leaving the steam turbine? (iv) calculate the entropy change in the steam as it passes through the turbine.

What precautions should you take to prevent injuries when dealing with heavy loads?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
