A person is working near the secondary of a transformer
$1.00A person is working near the secondary of a transformer . The primary voltage is 120 V at 60.0 Hz. The capacitance C, which is the stray capacitance between the hand and the secondary winding, is 20.0 ρF. Assuming the person has a body resistance to ground of Rb = 50.0 kΩ, determine the rms voltage across the body.
Determine the power developed by the turbine in hp.
$2.00Water vapor at 800 lbf/in^2 and 1000 degrees F enters a turbineoperating at steady state and expands to 2 lbf/in^2. The mass flowrate is 5.56 lb/s and the isentropic turbine efficiency is 92%.Stray heat transfer and kinetic and potential energy effects arenegligble. Determine the power developed by the turbine in hp.
Will the beam strike the moon?
$1.00A laser beam is to be directed towards the center of the moon, but the beam strays 0.25 degree from its intended path. The radius of the moon is about 1000 miles, and the distance from the moon to the earth is 240,000 miles. Will the beam strike the moon? (You may treat the moon as a flat disc for the purposes of this problem.)

Steam enters a partially open valve operating
$1.00Steam enters a partially open valve operating at steady state as saturated liquid at 300 degrees F and exits at 60 lbf/in^2. Neglecting kinetic and potential energy effects and any stray heat transfer with the surroundings determine the temperature, in degrees F, and the quality of the steam exiting the valve.

( Please ignore the line in the stray line between 2μF and εB.)Calculate the equivalent capacitance Cab between points a and b. Answer in units of μF.A 25 Kw series generator has an efficiency of 85%
$1.00A 25 Kw series generator has an efficiency of 85% when operating at rated load. If the stray-power loss is 20% of the full-load loss, calculate the efficiency of the generator when it is delivering a load of 15Kw, assuming that the stray-power loss is substantially constant and the other losses vary as the square of the load.
