1Ø CFM = Volts x Amps x 3.413 1.08 x Temp. Rise * 3Ø CFM = 1.73 x Volts x Amps x 3.413 1.08 x Temp. Rise * * = Difference between return and supply air temperatures. kW actual = kW rated * { Volts (actual) } 2 Volts (rated) NATURAL GAS COMBUSTION: Excess Air = 50%. 15 ft.3 of air to burn 1 ft.3 of methane produces:

A balanced 3 phase wye load is rated at . Is connected to a 440v, 3 phase system. Calculate VLine , Vphase , ILine , Iphase. VLine = 440v always the system voltage. Vphase = Iphase = ILine = Iphase = 25.4 A. The nameplate voltage and nameplate current for this load would be 440v and 25.4A respectively. A/C Power

A 3 phase Induction motor is running at 1740 rpm on a 60Hz supply. Calculate the no. of poles, the slip and the rotor frequency. The power supplied to a 3- phase Induction motor is 40 kw and the corresponding stator losses are 1.5KW. Calculate the total mechanical power developed and rotor copper loss if slip is 0.04 per unit.

Calculate the power draw (kW), reactive power (kVAr) and annual energy consumption (kWh/yr) of the motor. If motor were replaced with an energy-efficient 5-hp motor operating at 90% efficiency with a power factor of 85%, calculate the power draw (kW), reactive power (kVAr) and annual energy consumption (kWh/yr) of the “right-sized” motor.

Jun 17, 2002 · If this is a new installation, use shaded blocks in Table 2. Find starting KVA from Table 3. Find starting power factor from Table 2. Calculate KW starting = (KVA start) (PF start). To find starting KVA if only locked rotor amps are known; 1 phase. KVA start = (locked rotor amps) (voltage) 3 phase . KVA start = (3 ( locked rotor amps) ( voltage)
