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.
The cold cranking amperes (CCA) of a conventional lead-acid automobile battery is the amount of current the battery can provide at 0°F for 30 seconds and minute in at least 1.2 volts per cell (or 7.2 volts for a standard 12-volt battery). If a batter..
A constant-volume tank contains 10 lbm of ammonia initially at 30 lbf/in^2 and 80(deg)F (539.67(deg)R). The ammonia is then cooled until its pressure drops to 10 lbf/in^2. Determine its entropy change from the initial state to the final state.
