A certain tractor is capable of pulling with a steady force of $14.0 \mathrm{kN}$ while moving at a speed of $3.00 \mathrm{~m} / \mathrm{s}$. How much power in kilowatts and in horsepower is the tractor delivering under these conditions?

The figure shows that a mixed-flow pump is recommended for delivering $10000\ \mathrm{gal} / \mathrm{min}$ of water at a head of $40\ \mathrm{ft}$. If such a pump operates with a specific speed of $5000$, find the appropriate operating speed of the pump.

What type of single-phase motor develops the highest starting torque?

How is the combined pump-motor efficiency of a pump and motor system defined? Can the combined pump-motor efficiency be greater than either the pump or the motor efficiency?

How is the combined pump-motor efficiency of a pump and motor system defined? Can the combined pump-motor efficiency be greater than either the pump or the motor efficiency?

Why might a designer jacket worn by a movie star become popular with some people?

What is the trade-off between operator-performed maintenance versus supplier-performed maintenance?

Water flows at 3 m$^3$/s in a circular concrete sewer laid on a slope of 0.005. If a velocity of 2 m/s is desired in the sewer, calculate the diameter of sewer pipe that should be used. What would the depth of flow be in the sewer pipe?

Describe the essential elements of a mechanical face seal.

To measure the voltage across a resistor, how should the multimeter be connected to the circuit?

You are an electrician on the job. You have been given a multimeter that has the following AC voltage ranges: 30, 60, and 150. The meter states that it has a resistance of 5000ohm/v. You need to be able to measure a voltage of 277 volts.

How much resistance should be inserted in series with the meter to make the 30-volt range indicate a full-scale value of 300 volts?

What causes water to move from areas of higher elevation to areas of lower elevation? A. erosion B. thermocline C. gravity D. mixing
