Yes it is hard but please I need help with this A horizontal 8 cm OD pipe carries steam at 150°C through a room at 17°C. The pipe is covered by a1.5 cm layer of magnesia insulation. What is the heat loss per meter of the pipe?• For this configuration if a horizontal cylinder, NuD = f (RaD, Pr) can be found using equation 8.28• I assume since material and thickness of the pipe inside the insulation are not given, nor is any flow data onthe steam that these resistances are negligible.• The temperature of the outer insulation is not initially known. I guessed it and used a circuit diagram with tworesistances to find Q, then used one circuit to find the wall temp, and iterated. I updated my material propertieswith my wall temperature changes. It converged quickly.• My answer is 5-10% higher than the books. Not sure why.
Solution on all other sites including this site are wrong Only attempt if previously not attempted. Answer part a and b A) Among the nondimensional numbers, in free convection, average Nusselt number depends on only Grashof and Prandtl numbers. only Grashof number. Rayleigh number. Reynolds number. B) For ideal gases, the specific heat capacity at constant pressure, thermal conductivity, dynamic viscosity, and Prandtl number are independent of pressure. How will the ratio of thicknesses of velocity boundary layer and thermal boundary layer change if pressure is increased from 1 atm to 5 atm for the flow of an ideal gas over a flat plate? We need to know the actual fluid properties to tell It will remain the same. It will decrease by a factor of 5. It will increase by a factor of 5.
