A continues stream of water at $0C$ and a second stream at $60C$ are blended to yield $200$

$k\frac{g}{h}$ of water at $25C.$ Kinetic and potential energy changes are negligible.

$($a$)$ Calculate the flow rates of the two feed streams, assuming that the process is

adiabatic.

$($b$)$ Recalculate the flow rates assuming a heat loss from the mixture of $400k\frac{J}{h}.$
