Convert values to and from dozens of energy measurements.

There are a number of complex equations that deal with water pump engineering. Although not difficult to work with pen and paper, they can be time-consuming. This page eliminates much of the labor. Simply "plug in" your values in the blanks and press the "Calculate" button.

It calculates the maximum torque that can be transmitted by a clutch that is undergoing uniform wear. To use this calculator, enter value in empty boxes below then click on Calculate button to compute the maximum clutch torque.

High Speed Machining has brought major benefits to manufacturers and will continue to do so. However, with so much talk about high spindle speeds it is tempting to retrofit for as high a shaft speed as possible, but there are more things to to be considered in selecting the right spindle.

This calculator calculates the properties of welds when treated as lines.

The calculator computes ratios to free stream values across an oblique shock wave, turn angle, wave angle and associated Mach numbers (normal components, M_n, of the upstream).

This calculator uses Chézy and Manning's formula to calculate the wetted perimeter, hydraulic radius, flow area, Chézy coefficient and flow velocity.

The calculator computes ratios to free stream values across a normal shock wave and compares pressure and temperature variations across a normal shock wave between given state 1 and state 2.

The calculator computes the pressure, density and temperature ratios in an isentropic flow to zero velocity (0 subscript) and sonic conditions (* superscript). Select an input variable by using the choice button and then type in the value of the selected variable. The default input variable is the Mach number, and by varying Mach number you can see the effect on Mach angle. You can also select Mach angle as an input, and see its effect on the other flow variables.

The calculator will estimate the number of cubic yards that will be required.

The calculator will display the number of cubic yards required.

The calculator will estimate the number of cubic yards that will be required. Note that this is an estimate. There is significant variation in fill space among different blocks. This calculator assumes the use of double open-ended bond beam blocks.
