Saturated liquid water at 200 kPa enters an insulated mixing chamber at a rate of 15 kg/s. The water is mixed with superheated steam at 200 kPa and 125°C. The combined flow will exit as a saturated mixture at 200 kPa. Using your mixing chamber model to calculate the data, plot the quality of the combined exit flow for superheated steam entrance flow rates ranging from 5 kg/s to 200 kg/s.
State 1: Liquid inlet; State 2: Steam inlet; State 3: Outlet Given: P1 = P2 = P3 = 200 kPa; x1 = 0.0; T2 = 125°C; x3 = 1.0; m?1= 15 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. What will be an ideal response?
Name the process of joining two or more pieces of like metals by heating the material to a temperature high enough to cause softening or melting.
What will be an ideal response?
