Flow of an incompressible fluid is in the ry plane, and the y component of the veloc- ity, v, is given by v = 2y. (a) determine the required functional form of the velocity field. (b) give a particular velocity field that satisfies the required functional form.

A75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is to be replaced by a high-efficiency motor that has an efficiency of 95.4 percent. the motor operates 4368 hours a year at a load factor of 0.75. taking the cost of electricity to be $0.12/kwh, determine the amount of energy and money saved as a result of installing the high-efficiency motor instead of the standard motor. also, determine the simple payback period if the pu
