Problem $3)$ Two fluids enter a heat exchanger. The first fluid, steam, enters at a pressure of $3$

bar and a temperature of $160\backslash$deg C with a mass flowrate of $1\mathrm{.}5$ kg$/$s$.$ The steam leaves at the same

pressure but with a quality of $0\mathrm{.}75.$

a$)$ How much thermal energy is being transferred from the steam?

b$)$ If the second fluid, compressed liquid water at $25$ bar, has a temperature change

from $20\backslash$deg C to $40\backslash$deg C with a mass flowrate of $10$ kg$/$s$,$ what is the stray heat transfer?
