The fruit juice is heated in a heat exchanger using steam as a heating medium. The product flows through the heat exchanger at a rate of 1300 kg / hr and the intake temperature is 20 ° C. Determine the amount of steam required to heat the product to 100 ° C when only the latent heat of the vapor (assuming the inlet vapor temperature is equal to the temperature of the final product) is used for heating. The specific heat of the product is 4 kJ / (kg ° C). =
