A three-phase, wye-connected, cylindrical-rotor, synchronous motor, with negligible armature resistance and a synchronous reactance of 1.27 Ω per phase, is connected in parallel with a three phase, wye-connected load taking 50 A at 0.707 lagging power factor from a three-phase, 220-V, 60-Hz source. If the power developed by the motor is 33 kW at a power angle of 30°, determine:
(a) The overall power factor of the motor and the load.
(b) The reactive power of the motor.
The constant losses from a no-load run as a motor are given to be 220 W, of which 70 W represents friction and wind age losses. Calculate the efficiency of the induction generator.
2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
Suppose that both diodes have Rf = 10 Ω and Von = 0.5 V. Find the revised values of the resistors and voltage sources (v1 and v2) in order to accomplish the same objective.
The lower flammable limit (LFL) of methanol in air is 6.0 mole%. Calculate the temperature at which the equilibrium percentage of methanol vapor in a saturated methanol-air mixture would equal the LFL. (This temperature is a rough estimate of the ..
The uniform air gap is of length 1 mm, while the armature diameter is 0.5 m, and the axial length of the machine is 1.5 m. The field winding carries a current of 1 A (dc) and the rotor is driven at 3600 r/min.
A vapour stream that is 65 mole% styrene and 35 mole% toluene is in equilibrium with a liquid mixture of the same two species. The pressure in the system is 20 kPa. Use Raoult's law to estimate the composition of the liquid and the system temperat..
Calculate the gross torque developed for a flux per pole of 0.02 Wb and an armature current of 50 A. (Note: The number of parallel paths is equal to the number of poles for lap windings.)
From among the following, choose one which is not an exothermic process. 1. Ammonia synthesis 2. Methanol synthesis
Determine the angular velocity and angular acceleration of the blade at this instant
Comment on whether this motor is an induction motor or a synchronous motor.
a super tanker is 360m long and has a width of 70m and draft of 25m. assuming that the drag is mainly due to the skin friction at the bottom and side faces and that the boundary layer develops naturally,
