A standard door measures 3-ft-wide and 7-ft-height. If 15-mph wind is blowing against a closed door that opens outward, estimate the force (in lbs) required to start opening the door. Assume that the air pressure on the inside if the door is equal to the local atmospheric pressure, that the air temperature is 60 °F, and that the door handle is 3 ft from the hinge line.
