R 134a enters a air to fluid heat exchanger at 700 kPa and 50 oC. Air is circulated into the heat exchanger to cool the R134a to saturated liquid at 700 kPa. Ambient air at 20 oC and 100 kPa is circulated into the heat exchanger to cool the R134a. If The mass flow rate of R134a is 0.099 kg/sec and the circulated air increases in temperature by 5 oC, what is the volumetric flow rate of air through the heat exchanger

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.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
