Q$\mathrm{.}39$A shell and tube heat exchanger is used as a steam condenser. Coolant water enters thetube at $300$ K at a rate of $100$ kg$/$s$.$ The overall heat transfer coefficient is $1500$ W$/$mK$.$and total heat transfer area is $400$ m$.$Steam condenses at a saturation temperature of $350$ K$.$Assume that the specific heat of coolant water is $4000$ J$/$kg$.$K$.$The temperature of the coolant water coming out of the condenser is$($round off to the nearest integer$).$K
