An insulated pipe, D=33-cm-in diameter and L=13-m-long, is used to transport cold air at m=0.075-kg/s through a building. The pipe is isothermal at T,=37°C. Assume that the air flow is thermally and hydro dynamically fully developed. If cold air enters the pipe at 6°C, find the mean exit temperature air (in Kelvin). Note: Use the following as the mean properties of air: k = 0.0265 W/m.°C, v = 16 × 10-6 m²/s, Pr = 0.705 p=1.16 kg/m², c,=1008 J/kg.K, µ= 185 × 10-7 kg/s-m B Tm T,

A shell-and-tube heat exchanger is used to cool compressed liquid methanol from 176 °F to 104 °F. The methanol flows on the shell side of the exchanger. The coolant is water that rises in temperature from 50 °F to 86 °F and flows within the tubes at a rate of 68.9 kg s1. Finding the appropriate thermophysical data and applying the proper equations, you are required to do the following: (a) Calculate i) methanol mass flow rate in the exchanger, ii) methanol volumetric flowrate at the inlet of the exchanger. (b) i) For the counter-current flow of the fluids calculate the log temperature difference, ii) explain the purpose of calculating this difference, iii) explain, quantitatively, why is the counter-current flow in heat exchangers preferred to co-current flow. mean
