G If experimentally you measure the hydraulic gradient, Δp/L = 0.6832 m H2O/m, with a tube diameter = 3.00 mm and a mean measured flow velocity through the tube = 1.043 m/s; and rho= 997.0 kg/m3 and μ = 9.140 x 10-4 (N-s)/m2, what is the corresponding value of the friction factor, f ? Do not calculate this based upon a theoretical prediction, but from the definition of the friction factor and using these experimentally determined values

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
