Apump is used to transfer water from an open tank to a closed tank containing air at 500 kpa above the water. the pump has an efficiency of 80% and transfers 2000 l/min of water between the tanks. the water level in the two tanks is the same and you can assume that the tanks are large enough that the water level remains constant.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
