Acylindrical riser is to be designed for a sand casting mold. the length of the cylinder is to be 1.5 times its diameter. the casting is a square plate, each side = 12 in and thickness = 1.1 in. if the metal is cast iron, and the mold constant = 13.0 min/in2 in chvorinov's rule, determine the length of the riser in inches so that it will take 35% longer for the riser to solidify.

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.
