A heat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 250°C enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. Chlorine gas enters the exchanger at 1 bar and 33.0°C and leaves the exchanger at 132.0°C. Assume the heat exchanger is adiabatic. A)What is the specific enthalpy of the inlet steam stream? (Use liquid water at 0.01°C as a reference...

Determine the overall heat transfer coefficient (U) in a heat exchanger that uses steam to heat water to the point of vaporization (in vacuum.)
Determine the overall heat transfer coefficient (U) in a heat exchanger that uses steam to heat water to the point of vaporization (in vacuum.) The system is non-insulated, so the heat lost to the surroundings must be taken into consideration. While I know that the heat Q = mCdT and the heat transfer rate q = UAdT(Log-mean), I am struggling to equate the two due to the heat lost to the surroundings. How do I go about determining the overall...
