Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam is leaving a pressure cooker whose operating pressure is 20 psia. It is observed that the amount of liquid in the cooker has decreased by 0.6gal in 45 minutes after the steady operating conditions are established, and the cross-sectional area of the exit opening is 0.16in2. The properties of saturated liquid water and water vapor at 20 psia are vf=0.01683ft3/lbm,vg=20.093ft3/lbm,ug= 1081.8Btu/lbm, and hg=1156.2Btu/lbm. Determine the mass flow rate of the steam and the exit velocity. (You must provide an answer before moving on to the next part.) The mass flow rate of the steam is 103lbm/s. The exit velocity is ft/s
