A steam pipe of 120 mm outside diameter and is covered with a 20 mm thick layer of calcium silicate insulation (k = 0.089W/m * K ). The surface temperature of the pipe is 800 K, and the ambient air and surrounding temperatures is 300 K.The convection coefficient is 5.5 W/m^2 *k and radiation coefficient is 10 W/m^2 * k. Determine the heat rate per unit length from the pipe (W/M) and the insulation outer surface temperature (K).

a nozzle is a device that is used to increase the velocity of a flowing fluid. it does this by reducing the pressure.
one kilogram of saturated liquid methane at 160 k is placed in an adiabatic piston-and-cylinder device and the piston
