Water flowing in a horizontal 25-cm-diameter pipe at 9 m/s and 300 kpa gage enters a 90° bend reducing section, which connects to a 15-cm-diameter vertical pipe. the inlet of the bend is 50 cm above the exit. neglecting any frictional and gravitational effects, determine the net resultant force exerted on the reducer by the water. take the momentum-flux correction factor to be 1.04.

What is the main objective of using reheat rankine cycle?

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
