An ideal regenerative Rankine cycle uses an open feedwater heater operating at a pressure of 400 kPa. The minimum Pressure in teh cycle is 50 kPa while the maximum is 5 MPa. If 82.5 MW of heat is added in the boiler which has a mass-flow rate of 25 kg/s, determine the maximum temperature in the cycle (range

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Which one from below is not one of the reasons of planning failures? (clo3) a)-planner is careless. b-planner spend less time in the field but more time on the desk c)-planner is not qualified d)-planner does not have sufficient time to properly plan
