Superheated steam flows steadily through steel tubing (k 35 W/m-K) applying a tube inner surface temperature of 575°C. The tubing has an inner diameter of 300 mm and a wall thickness of 30 mm. Insulation (k 0.10 W/m-K) is applied to the outer surface of the tube while thin aluminum sheet is applied around the insulation as a protective covering. The ambient air at 27°C provides a convection coefficient of 6 W/m2-K. Determine the minimum insulation thickness necessary (mm) to...

Question 2 (30 marks) (a) A fluid flowing into a nozzle with specific enthalpy of 2980 kJ/kg and the velocity is 80 m/s. At the exit of the nozzle, the specific enthalpy of the fluid drops to 2670 kJ/kg. The nozzle orientation is horizontal and the heat loss is negligible. Given that the nozzle inlet area is 0.25 m2 and the specific volume of the fluid is 0.2 m2/kg, calculate the velocity of the fluid at exit, the mass flow...
