Sugar is ground from crystal which can pass through 500µM sieve down to a size which is acceptable that 80% passes through 88µM sieve, and a 5horsepower motor is found just sufficient for the required throughput. If the requirements are changed such that the grinding is only down to 80% through a 125 µM sieve but the throughput is to be increased by 50%. Decide whether the existing motor has sufficient power to operate the grinder. Assume Bonds equation
