= A 1.2 lbm/s stream of toluene at T = 100 F and P = 1 atm needs to be heated to 175 F and P = 1 atm, as that is the temperature at which it must enter a chemical reactor. This heating process is to be carried out in a shell and tube heat exchanger with steam at P= 1 bar and T = 300 C to be used as the source of heat. Determine the flow rate of entering stream if the steam exits the heat exchanger as saturated vapor at P= 1 bar. Specific heat capacity: steam = 2030 J-kg-1.0C-1, toluene = 1595 J.kg 1.00-1 -C- =
