A shell and tube heat exchanger is used as a steam condenser. Coolant water enters the tube at $300 \text{ K}$ at a rate of $100 \text{ kg/s}$. The overall heat transfer coefficient is $1500 \text{ W/m}^{2}.\text{K}$, and total heat transfer area is $400 \text{ m}^{2}$. Steam condenses at a saturation temperature of $350 \text{ K}$. Assume that the specific heat of coolant water is $4000 \text{ J/kg.K}$. The temperature of the coolant water coming out of the condenser is __________________ $\text{K} (\textit{round off to the nearest integer}$).
