During the solution treating of steel materials, which of the following statements are true: (a) the rapid cooling aims to create a hard shell of the parts; (b) the quenching could potentially result in metastable martensitic microstructure; (c) the quenching should be carried out in water; (d) the purpose of initially heating up the material to high temperature is to relieve stress sufficiently; (e) the subsequent aging procedure promotes microstructural evolution from metastable phases to more stable phases.

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.
