Air at 150°C is heated as it flows through a tube with a diameter of 5 cm at avelocity of 5 m/s. Calculate the heat transfer per unit length of tube if aconstant heat flux condition is maintained at the wall and the walltemperature is 54'C above the air temperature, all along the length of thetube. The properties of air at the bulk mean temperature are as follows:

The pressure of a reactor vessel can be adjusted bychanging either the inlet or outlet gaseous flow rate. Theoutlet flow is kept fixed as long as the tank pressure remainsbetween 100 and 120 psi, and pressure changes are treatedby manipulating the inlet flow control valve. However, if thepressure goes higher than these limits, the exit gas flow isthen changed. Finally, if the pressure exceeds 200 psi, a ventvalve on the vessel is opened and transfers the gas to a storagevessel. Design a control scheme that meets the performanceobjectives.
