An alumnus of your engineering program has donated money to build a jogging track that would encircle your campus. The track will be made of a recycled rubberized material. How much of this rubberized material will be needed?
Set up the problem in polar coordinates assuming no circumferential variations, and show that the vorticity in the fluid is given by (see attachments).
the liquid in a pool has a linearly varying density of the form pz a bz where z is the depth in meters and the
a normal shock wave exists in mach 2 stream of air having temperature and pressure of 45degf and 30 psia respectively.
Water enters one stream of an unmixed stream heat exchanger at 20°C and increases in temperature by 10°C. Air enters the second stream on the heat exchanger at 400°C and 5 kg/s. The air temperature at the exit of the heat exchanger is 200°C cooler th..
A closed, rigid tank fitted with a paddle wheel contains 0.1kgof air, initially at 300 K, 0.1MPa. The paddle wheel stirs the air for 20 minutes, with the power input varying with time according to W = -10t, where W is in watts and t is time, in minut..
Assuming a small oscillation about the horizontal equilibrium position, determine position X for the slider such that the friction period is 1 second.
Determine the uncertainty in the determination of the two specified temperatures. State the relative influence of instrument uncertainty and surface emissivity uncertainty.
Water flowing through a 10-cm-diameter water pipe at a rate of 0.1 m3/s. Now a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water. The inlet side of the pipe is part of a continuous piping system (so that th..
