Steel plate measuring 1m by 2m and of 5mm thickness intitailly at 500 degress C need to be cooled by air at 50 deg C and blowing at 20m/s. The air blows paraale to the shorter wdge. Estimate the convenction coeffiecient and thje initail cooling. The viscocity, specific heat and theraml conductivity of air at 275 deg C are 2.88E_)% Pa/s 1040J/kg/K and 0.0439 W/m/,respectively. Estimate the desnity of air using thre ideal gas law (R

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.

Aheavily insulated piston-cylinder device contains 0.02 m3 of steam at 300 kpa and 200 °c. 1.2 mpa. d this process. team is now compressed in a reversible manner to a pressure of etermine the entropy change and the work done on the steam during this process

What is creep? what is stress relaxation?
