Steam in the condenser of a thermal power plant is to be condensed at a temperature of 30°C with cooling water which enters the tubes of the condenser at 14°C and exits at 22°C. The total surface area of the tubes is 50 m2, and the overall heat transfer coefficient is 2000 W/ m2. The heat transfer (in MW) to the condenser is ______(correct to two decimal places).
