3. Nitrogen flows from a large tank, through a convergent nozzle of 2 in. tip diameter, into the atmosphere. The temperature in the tank is 200 F. Calculate pressure, velocity, temperature, and sonic velocity at the exit, and calculate the flow rate when the tank pressure is (a) 30 psia and (b) 25 psia. Barometric pressure is 15.0 psia. What is the lowest tank pressure that will produce sonic velocity in the jet

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
