Question

HELP!!! dont have time for this hw

The following per phase (single phase) equivalent circuit is for a 5 HP. 60 Hz., 440 VAC 3 phase induction motor. The motor was operating at rated load and the speed of the rotor was measured to be 1753 RPM. Write a program using Math Cad, MATI-AB, or Excel to solve the equivalent circuit above using many values for the slip between 0.001 and 1.00. Remove the power factor correction capacitor for this analysis. Graph the following purarueteis on an xy plot (use appropriate axes titles): 3 Phase Torque (N-m) vs Speed (RPM) Current (Amperes) vs. Speed (RPM) much (HP) vs Speed (RPM) Efficiency (%) vs. Speed (RPM) Power Factor (%) vs. Speed (RPM) Draw the power triangle for this machine (include VA, VARS, WATTS, and power factor angle) for the operating point described in the problem description. Calculate the capacitor required to correct the power factor to unity.
