In a single pass shell and tube heat exchanger, fresh water is used. refrigeration to condense an organic vapor. under operating conditions current, the heat transfer coefficients are ho = 2000 W/m2K (turbulent flow of cooling water), hi = 700 W/m2K. Fouling is negligible and the tubes are of 1.25-inch schedule 40 carbon steel. Water flows into shell. If the water rate of cooling by suddenly increasing by 15%, calculate the change in the coefficient of full heat transfer.
