Local resistance in a pipe section is resistance at fittings, valves, equipment, etc. Head losses on local resistances are calculated by the formula: where Δpms. - loss of pressure on local resistances, Pa;
Web12 de nov. de 2013 · My calculation for amps in each leg is 15KW*1000/ [208V*1.73] = 41.7 amps. On each leg there is a thermal limit switch with 25 amp rating. Since I1 = I2 = I3 = 41.7 amps in each leg, I need to split into two branches to divide the amps into two because of the 25 amp limit switch.

WebWe can calculate the resistance required for our heater by rearranging Ohms's Law to R = V I. For our 100 W, 100 V heater we get R = 100 1 = 100 Ω. For the 200 V model we get R = 200 0.5 = 400 Ω. The part to watch is that power for a given resistor is proportional to the square of the voltage or current.
WebThe rated PTC resistance is normally defined as the resistance at 25 °C. It serves to classify the thermistors according to their resistance value. It is measured with a low current that does not heat the thermistor enough to affect the measurement.
