Cooling water flows through the tube of a condenser at such a rate that the inside film coefficient is 1300 btu/hr-sq ft f. the tube has an ok of 0.875 in. and a well thickness of 0.0375 in. the thermal conductivity of the tube metal is 64.0 btu/hr ft f. steam condenses on the outside of the tube with a film coefficient of 2000 btu/hr-sq ft f. what’s the overall film coefficient based on the outside tube diameter?
