d.i.y. 250 kV High Voltage DC Power Supply with Neat Trick ...· In this AC power supply, a push-pull oscillator drives a TV flyback transformer from an old color TV (a flyback without embedded tripler). The well-known hack is that the original primary of the flyback is not used. Instead, new primaries are made by winding two sets of four turns each of insulated #18 wire around the exposed core of the ...
Leak rate calculator - LMNO Eng rate is one application where it is widely used. Since a pipe is usually much larger diameter than the hole, V 2 >>V 1. Since the elevation change Z 2-Z 1 is typically very small compared to other terms in the Bernoulli equations for a pipe leak application, Z 2-Z 1 =0. Thus:
