Two bosses in a plastic bezel must align with two mounting holes in a steel plate. The steel plate holes are 8 inches apart center to center. What should be the center to center distance of the core pins that make bosses of the plastic part?
You have a container of gas with a molar volume of V¯=0.12 dm3·mol-1 at a temperature of T=280 K. You know that for this gas, 280 K corresponds to a reduced temperature TR=1.5 and that you are applying a reduced pressure of PR=4. Using your knowledge..
For T 5 808F, determine the steam quality at the turbine exit, the steam mass flow rate, in lb/h, and the thermal efficiency. Plot the quantities of part (a) versus T ranging from 80 to 1058F.
