Explain how to check a spool valve for proper fit in its respective bore.
What will be an ideal response?
Hold the valve body vertically and install an unlubricated valve into its bore. Let the valve fall of its own weight into the valve body until the valve stops. Then, place your finger over the valve bore and turn the valve body over. The valve should drop by its own weight.

Compressed liquid water at 1000 kPa and 30°C enters an insulated mixing chamber at 50 kg/s. The water is mixed in the chamber with superheated steam at 1000 kPa. The combined flow exits as a saturated liquid at 1000 kPa. Using your mixing chamber model to calculate the data, plot the mass flow rate of the superheated steam for entering steam temperatures ranging from 200°C to 500°C.
State 1: Liquid inlet; State 2: Steam inlet; State 3: Outlet Given: P1 = P2 = P3 = 1000 kPa; T1 = 30°C; x3 = 0.0; m?1= 50 kg/s Assume: Q?=0 (insulated). Given no other information regarding the mixing chamber, make the following common assumptions: W?=?KE=?PE=0 Also, assume the mixing chamber is a multiple-inlet, single-outlet, steady-state, steady-flow device.
