A 440-V, 3-φ 50-Hz, 4 poles, 37.3 kW, Y-connected induction motor has the following parameters:
R1= 0.1 Ω, X1 = 0.4 Ω , R2′ = 0.15 Ω , X2′ = 0.44 Ω
Motor has stator core loss of 1250 W and rotational loss of 1000 W. It draws a no-load line current of 20 A at a p.f. of 0.09 (lag). When motor operates at a slip of 3%, calculate
a. input line current and p.f. [57.4@29°A, 0.875 lag]
b. electromagnetic torque developed in N-m [230 Nm]
c. output and [34075 W]
d. efficiency of the motor. [88.7%]

Which has the greatest NPV assuming a 25 year planning horizon and MARR = 12%?

Install a $20,000 solar system that will last 25 years, and generate 38,000 kWh/year at $0.10/kWh.
Install a $25,000 Ground-Source Heat pump that will last 50 years and save $3,500/year.
Both options has equal NPV
Not possible to be calculated

Design a sequential traffic light controller for the intersection of street A and street B. Each street has traffic sensors which detect the presence of vehicles approaching or stopped at intersection.

Sa=1 means a vehicle is approaching on street A.

Sb=1 means a vehicle is approaching on street B.

There are 3 outputs of each streets RedA, YellowA and GreenA, RedB, YellowB, and GreenB.

Condition: “StreetA” is a main street and has a green light for at least 50s, after 50s if there is a car approaches on “StreetB”, the light changed to yellow then red and “StreetB” has green light for 50s.

At the end of 50s, the light change back unless there is a car on “StreetB” and none on “StreetA”

Present the code and develop a waveform using the Quartus Prime 19.1 Lite edition.
