Here is a computerized version of the Moody Chart, which can prove very useful in the determination of Darcy friction factors for a variety of pipe sizes and materials with different roughness heights. Darch friction factor is crucial in pressure drop calculations for turbulent pipe flows. This Moody chart solver solves implicit Colebrook Equation and shows a graphical visualization as well.

This small tool allows you to calculate different fluid properties, such as dynamic viscosity, density, kinematic viscosity, specific heat, thermal conductivity, thermal diffusivity of a variety of fluids at a given temperature. It also provides Prandtl number and Reynolds number (provided velocity and length scales are provided).

Here is an interactive tool that computes the anchor force on an aircraft test engine because of the momentum changes between inlet and outlet. The users can vary not only the inlet velocity (i.e. the aircraft speed), but also the area of the inlet as well as the outlet section. Similarly, the gage pressure at inlet and outlet sections can also be entered, and the corresponding changes in the anchor (/thrust) force observed.
