For Problems15−28, perform the indicated conversion of units. (Refer to Appendix 16 for conversion factors.) Express the results with the appropriate prefix as illustrated in Tables1−3 and 1−4.

26. To compute the energy used by a motor, multiply the power that it draws by the time of operation. Consider a motor that draws 12.5 hp for 16 h/day, five days per week. Compute the energy used by the motor for one year. Express the result in  $\text{ft}\cdot \text{lb}$ and $\text{W}\cdot \text{h}$ .
