Question: A converging nozzle is attached to a reservoir containing helium with T0=27°C and p0=200 kPa absolute. Determine the receiver pressure that will just give Me=1. Now attach a diverging section with a 15-cm-diameter exit to the 6-cm-diameter throat. What is the highest receiver pressure that will give Mt=1?
How fast will it be going when it hits the ground?
A pressurized steel tank has a radius r=0.6m, a wall thickness t=18mm and an internal pressure p of 2.8 MPa.The steel has a modulus of elasticity E of 200 GP and a poissons ratio 0.30.Determine the hoop and axial stressses
If the elevation of the instrument station is 285.69 ft and the heights of the instrument, EDM, target, and reflector are all equal to 5.08 ft, compute the elevation of the target station and the horizontal distance to that station.

Using the solubility data of a solid in a specified liquid, explain how you would determine the mole fraction of the solid in the liquid at the interface at a specified temperature.
The engineer in charge of this project investigated severla alternatives to cool the exhaust gas and has concluded that the two most practical solutions would be either the installation of a waste heat boiler or the installation of a spray injecti..
A key part of the FEM and any FEA model are the appropriate assignment of boundary conditions. Explain why it is necessary to set the appropriate boundary conditions in FEA simulations. What happens if you don't assign boundary conditions or assig..
The power plant in Problem 9.16 has too low a quality in the low-pressure turbine section, so the plant wants to apply reheat at 800 kPa. What should the superheat for the reheat be so that the turbine quality stays above 92%?
