iFunctionGenerator turns your iPhone, iPad, or iPod Touch into an audio function generator. You can have up to 20 generators, each operating at a different frequency. Each generator can be one of the following types: • Sine Wave • Triangle Wave • Sawtooth Wave • Square Wave • Pink Noise • White Noise The volume of the left and right channels can be independently controlled, and may be set using either a slider for ease, or direct entry of the volume, for maximum precision. The relative phase of each channel may also be set. Frequencies from 1 to 20,000 Hz may be entered. The phase can vary between -360 to 360 degrees. The volume may be between 0 and 100 percent. The mute button makes it easy to quickly silence the audio generators. You can take snapshots of the generator settings. This lets you build a library of settings, and quickly load the desired settings.

Darcy-Weisbach Equations for Hydraulics Fluid Mechanics In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss or pressure loss due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. Darcy-Weisbach equations are used to calculate the major pressure or head loss due to friction in pipes, ducts, or tubes. Formula: h = fLv²/2Dg Where: h - is the head loss f - is the friction factor L - is the pipe length D - is the pipe diameter v - is the flow velocity g - is the acceleration of gravity Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.
