A) A coil connected to a 250-V, 50-Hz sinusoidal supply takes a current of 10 A at a
phase angle of 30°. Calculate the resistance and inductance of, and the power
taken by the coil.
b) A voltage v = 0.95 sin754t is applied to a series RLC circuit, which has L = 22.0
mH, R = 23.2 k2, and C = 0.30 uF.
(i) What is the impedance and phase angle7 element?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
