Energy required to convert water to saturated steam
How much energy is required to convert water at 30 GC (and at atmospheric pressure) to saturated steam at 169.06 kPa and 85% quality?

At what RPM should the model be run? What is the required impeller diameter ratio between the model and prototype and what is the volume flow rate through the model if the efficiency is 0.88?
What is the correct speed at which the compressor must run? If inlet pressure of 90 kPa is obtained at a point where the normal ambient condition mass flow would be 60 kg/s, calculate the mass flow rate obtained during the test.
However, test conditions limit the available power to 400 kW and 1 m3/s flow of water. Assume model and prototype efficiencies are the same. Find the head and speed of the model.
Monkey B is climbing up with a constant speed of 3.8 ft/sec. Treat the rope and monkeys as a complete system and calculate the tension T in the rope at D.
Sketch a venn diagram of these events, Berkeley and Chelsea visited independently of one another.
A charged particle leaves the origin with a speed of 2.91 x 106 m/s at an angle of 33° above the x axis. A uniform electric field, given by = -E0, exists throughout the region.
Assume the poisson distribution applies. Use the given mean to find the indicated probability.
Determine the ratio of gross thrusts (contribution to engine thrust made by the exhaust nozzle only) for: a. The nozzle is converging-diverging with the area ratio for correct expansion to ambient pressure.
