A lift on Mars for unloading spacecraft has a height of 8 feet [ft], and a floor area of 10 feet [ft] wide by 6 feet [ft] long. The lift floor is made of a thin sheet-metal that has a maximum pressure rating of 0.5 pounds-force per square inch [psi]. A crate of material of with a mass of 5000 pounds-mass [lbm] on Earth, with measurements of 4 feet[ft] high by 8 feet [ft] wide and 4 feet[ft] long , is shipped to Mars. The acceleration due to gravity on Mars is 3.7 meters per second squared [ms2]. Can the crate be safely removed from the spacecraft once it reaches Mars using the lift? To support your answer, determine the pressure of the crate in units of pounds-force per square inch [psi].
A freezer with dimensions of 4 m wide, 6 m long and 3 m high is under construction. The walls and ceiling are composed of 1.7 mm stainless steel (k = 15 W / [m ° C]), 10 cm thick foam insulation (k = 0.036 W / [m ° C]), a specific thickness of corkboard (k = 0.043 W / [m ° C]), and 1.8 cm thickness of wood (k = 0.104 W / [m ° C]). The inside of the freezer is maintained at -40 ° C. The ambient air outside the freezer is 32 ° C. The convective heat transfer coefficient is 5 W / (m K) on wooden walls and 2 W / (m² K) on stainless steel surfaces. If the outside air has a dew point of 29 ° C, calculate the thickness of the corkboard insulation that will prevent moisture condensation on the outer walls of the freezer. Calculate the heat transfer rate through the walls and ceiling of this freezer. Ignore heat transfer from floors and corners of buildings. a. Thickness of corkboard insulation = cm. b. Heat transfer rate through walls and ceilings = watt.
