To determine
The full load running current of the motor.
Expert Solution & Answer
Explanation of Solution
Given information:
Horsepower is
Armature voltage rating is
Solution:
Refer Table 430.247 “Full Load Current in Amperes, Direct Current Motors” from page 368 and obtain the full load current in amperes corresponding to the horsepower of 20 HP and the armature voltage rating of 500V as follows:
Thus, the full load running current of the motor is

- This is an old exam review problem. Please helparrow_forward3. The volumetric flow rate of air through a duct transition of the type shown in Table 12-9b (rectangular with two parallel sides) is 2 m3/s. The duct before the transition issquare, with a height of 50 cm. The expansion ratio across the transition is 4 (i.e., theduct area after the transition is 4 times greater than the duct area before the transition).a) Determine the pressure loss (in Pa) across the transition if the exit from the duct isabrupt (i.e., the diverging angle of the transition is 180º).b) Determine the percentage reduction in pressure loss for a transition diverging angleof 20º compared to the one in part (a).c) The head HVAC engineer requires the pressure loss across the transition to bereduced to less than 50% of the pressure loss for an abrupt exit (i.e., the case in part(a)), and suggests a transition diverging angle of 45º. Will this new diverging angleachieve the required reduction in pressure loss?

- Mini project You are an engineer working for a power systems company responsible for ensuring grid stability. Your team has recently observed low-frequency oscillations in the system following disturbances such as load changes, faults, and switching operations. These oscillations have led to voltage instability, frequency deviations, and, in severe cases, system blackouts. A task force has been formed to address this issue, and you have been assigned a critical role in developing a damping control strategy. Your objective is to analyze system performance, propose engineering solutions, and compare the effects of different damping approaches. Answer the following questions 1. Identify the Engineering Problem: - What is the fundamental issue affecting power grid stability? - How do low-frequency oscillations impact the system's reliability? - What parameters indicate system instability? 2. Assess the Current Status Using Equations and Calculations: - Given the characteristic roots of the…arrow_forwardH.W 4: The beam shown below is subjected to the distributed loading of w=120 kN/m.

The temperature of the outside room is 30°C, and the combined convection and radiation heat transfer coefficient at the surface of the outer wall is 10 W/m2°C. It is proposed to insulate this section of the furnace wall with glass wool insulation (k = 0.038 W/m°C) in order to reduce the heat transfer by 90%. Assuming the outer surface temperature of the cold room wall section still remains at about 7°C, determine the thickness of the insulation that needs to be used.arrow_forward
