g Air is blowing over a smooth flat plate, and the Reynolds number at the end of the plate is found to be 1x106 . Sketch how the convective heat transfer coefficient varies along the flow direction.

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.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?
