A single phase, 50-KVA, 2400-240-volt, 60 Hz distribution transformer has the following parameters: Resistance of the 2400-volt winding Ri=0.75 ohm Resistance of the 240-volt winding R=0.0075 ohm Leakage reactance of the 2400-volt winding X:=1 ohm Leakage reactance of the 240-volt winding X2=0.01 ohm Core loss resistance on the 2400 side Rc=733.5 ohms Magnetizing reactance on the 2400 side X=4890 ohms a. Draw the equivalent circuit referred to the high voltage side and referred to the low- voltage side. Label the impedances numerically. b. The transformer is used as a step-down transformer at the load end of a feeder having impedance of (0.5+j2.0) ohms. Determine the voltage V. at the ending end of the feeder when the transformer delivers rated load at rated secondary voltage and 0.8 laggin power factor. Neglect the "exciting current" l. of the transformer (this is the current into the parallel Rc/jXm combination), which is another way of saying that you should use what we called in class the "approximate circuit #2).

Design a U-tube manometer that can measure gage pressures up to 69 kPa of air. You will want to choose a manometer fluid with good static sensitivity but will not result in an unreasonably tall manometer. Further, the manometer fluid should be mostly immiscible with the air. The two design parameters you should consider are manometer fluid (impacts manometer fluid density) as well as the manometer height. Required:Compute the static sensitivity, K, in mmHg/Pa

Large wind turbines with blade span diameters of over 100 m are available for electric power generation. Consider a wind turbine with a blade span diameter of 100 m installed at a site subjected to steady winds at 8 m/s. Taking the overall efficiency of the wind turbine to be 32 percent and the air density to be 1.25 kg/m3 , determine the electric power generated by this wind turbine. Also, assuming steady winds of 8 m/s during a 24-hour period, determine the amount of electric energy and the revenue generated per day for a unit price of $0.09/kWh for electricity
