In a faraway land an engineer is observing a construction working on a snow from a pavement. What he is doing is he is transferring those snows a height of 305 cm using a unique scooper to the container. At the highest point, he notice that these bulk snows has a speed of 3 ft/s. He was informed that to maintain a scooping rate of 100 lb/s he needs 24.61 kw. If we assume that there is friction resulting to the total loss of 10%. Determine the total work done and the percentage of total work need to melt and break up the snow. Assume that the energy need to melt the snow is 144 Btu.
