Unformatted text preview: ﬁnal temperature of 400 K. Calculate the heat transfer from the system and the ﬁnal system pressure. 3. Methane enters a heater at 298 K, 1 atm pressure with a volumetric ﬂow rate of ˙ V = 50 cc/s. The fuel is mixed with air at the same temperature and pressure, and the mixture has an equivalence ratio of Φ = 0 . 9. Using a constant speciﬁc heat for the products of c P = 1 . 05 kJ/kg K, calculate and plot the rate of heat transfer from the heater as a function of product exhaust temperature, for T P = 298 K to 400 K. Be sure to include the eﬀect of water condensation in your result. The MATLAB steam functions will be useful in this assignment. 1...
