Laminar, fully developed flow from a tube impinges on a flat rigid surface. The figure shows a cross section of this flow with inlet radius Ro.
The entire region 0 < z < B is filled with the fluid that comes from the downward pointing vertical jet.
Find:
a. how would I get the stream function formulation for this flow (donotsolveit).b. What boundary conditions would you use at , assuming R>>B.
A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: There are no significant changes in kinetic or potential energy.
Water is the working fluid in an ideal regenerative Rankine Cycle, as shown. Superheated vapor enters the turbine at 10 MPa and 480°C, and the condenser pressure is 6kPa.
for the vapor power cycle steam enters the at 3 mpa and 500 c and leaves at 70 kpa and 200 c. the system is operating
approximately 250 mol of an ideal gas expands adiabatically and irreversibly from 2 m3 to 5 m3 against a constant

You arrive home from a winter trip and turn on your baseboard (resistance coil) heater to warm the room. It remains on for 52 minutes, during which time it steadily consumes 3 kW of electricity. How much energy was transferred to the room in kJ?
A jet of water issues from a nozzle at a speed of 6 m/s and strikes a stationary flat plate oriented normal to the jet, as shown in Figure 1. The exit area of the nozzle is 645 mm2. Ignore friction losses and assume all pressures are atmospheric (zer..
