Superheated vapor is flowing at a rate of 0.3kg/s inside a pipe with 5cm in diameter and 10m in length. The pipe is located in a power plant at T=20C, and has a uniform pipe surface temperature of 100C. If the temperature drop between the inlet and exit of the pipe is 30C, and the specific heat of the vapor is 2190J/kgK2 determine the heat transfer
