The engine's total efficiency would be 90hp/.90 = 100hp. But the question is how much money is being lost due to engine inefficiencies. So we deduct the 90hp output from the 100hp output, which would be 100% efficient, and get 10hp. Inefficiency results in a loss of 10hp.
The solution is 5,968 watts divided by 746 watts.
Power Output divided by Efficiency = PO/E 100/.5 = 200lbs
660N is multiplied by 30m.
12 lbs. Because the containers are of same size and are pressured, the weight will be distributed uniformly.
To get the answer in pounds, multiply 115.5 by 2,000 (231,000 lbs). Next, divide that by the number of pounds a single horsepower can move every minute, which is 33,000.
