In winter season, he chemical observed a snow from a pavement that is being scooped up to a height of 40 ft by an endless bucket-scoop. and is then dropped into a container. He noticed that, at the highest point, the snow moves at 3 k’s. A total of 66 hp is needed to scoop snow at the rate of 100 lb’’s. Assuming a loss of 10% due to friction, calculate the percentage of tool work need to melt and break up the snow.
