Flowrate Calculation for a Draining Tank
Hydrostatic pressure will impart a velocity to an exiting fluid jet. The velocity and flowrate of the jet depend on the depth of the fluid.

Flowrate Calculation for a Venturi
A fluid passing through smoothly varying constrictions experience changes in velocity and pressure. These changes can be used to measure the flowrate of the fluid.

Flowrate Calculation for an Orifice Flowmeter
A fluid passing though an orifice constriction will experience a drop in pressure across the orifice. This change can be used to measure the flowrate of the fluid.

Fluid Flow Calculator
Calculate basic fluid flow problems involving hose.

Fluid Force On A Plane Surface
The Applet will calculate the weight needed to keep the apparatus in equilibrium so that the experimental pressure force can be calculated by statics.

Pipe Friction Calculation for Fluid Flow in a Pipe
Wall drag and changes in height lead to pressure drops in pipe fluid flow.

Pipe Roughness Data
Included here is a sampling of absolute pipe roughness e data taken from Binder (1973). These values are for new pipes; aged pipes typically exhibit in rise in apparent roughness. In some cases this rise can be very significant.

Pressure Calculation for Manometers
Manometers measure a pressure difference by balancing the weight of a fluid column between the two pressures of interest.
