What will be an ideal response?
Liquid water at 10°C enters an insulated mixing chamber at a rate of 180 kg/s. In the chamber, the water is mixed with a second stream of liquid water, which enters at 90°C. Using your mixing chamber model to calculate the data, plot the exit temperature of the combined stream for mass flow rates of the second stream ranging from 20 kg/s to 500 kg/s.
State 1: Cool Liquid inlet; State 2: Warm Liquid inlet; State 3: Outlet Given: T1 = 10°C; T2 = 90°C; m?1= 180 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.
