An oil pump is drawing 44 kw of electric power while pumping oil with rho = 860 kg/m3 at a rate of 0.1 m3 /s. the inlet and outlet diameters of the pipe are 8 cm and 12 cm, respectively. if the pressure rise of oil in the pump is measured to be 500 kpa and the motor efficiency is 90 percent, determine the mechanical efficiency of the pump.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
