Consider an adult person standing in a room at 25°c. determine the total rate of heat transfer from this person if the exposed surface area is 1.6 m2 and the skin temperature of the person is 32°c, and the convective heat transfer coefficient is 4.8 w/m2-k. take the emissivity of the skin and the clothes to be 0.85. the temperature of the inner surfaces of the room are 28°c. now consider a child that is present in the room and whose skin temperature is the same as the adult, but whose surface area is 40% less than the adult. by what percentage does the total rate of heat transfer change for the child compared to the adult? you must show all of your work to get credit.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
