1.laminar flow of a real fluid down a cylindrical pipe of constant radius R. Poiseuille showed that the velocity profile was parabolic and given by u(r)=c(R^2-r^2), where r is the radial coordinate and c is a dimensional constant. what is the mean momentum flow rate down the pipe?
2.Provided that the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about 20 Hz to about 20000Hz. Compute the wavelength corresponding to these frequencies a.) for waves in air ( v= 344 m/s); b.) for waves in water ( v=1480 m/s).
A distance of 72.55 ft is recorded using a steel tape weighing 0.016 lb per foot. The tapes is supported only at the ends with a tension of 15 lb. Find the distance corrected for sag.
How to use the bisection method on the van der waals equation Problem The van der Waals equation gives a relationship between the pressure P (in atm.),
You are assigned the task of using bioremediation to cleanup a hazardous waste site contaminated with Tetrachloroethylene. The site is a shallow surficial sandy aquifer 30 feet deep underlain by a clay unit. The depth to the watertable is 10ft.
A tangent section of highway has a -1.0% grade and ends at station 0+1450and elevation 25m. It must be connected to another section of highway that has a -1% grade and that begins at station 1+345 and elevation 40m.
A concrete cylinder having a diameter of 6 in and a gauge length of 12 in is tested in compression the results of the test are reported in the table as load vs contraction
At what depth would the vertical effective stress in a deep deposit of clay be 100 kpa, if e=1.1? The ground water level is a 1 m delow ground surface and S=95% above the groundwater level. Neglect pore air pressure.
Find the magnitude and depth of the point of application of the force on the circular gate shown (circular gate at an angle of 60 deg.) if h(distance from top of gate to top of water)=5ft. and D(length of the gate)=4 ft.
A single crystal of a FCC metal is oriented so that the [001] direction is parallel to an applied stress of 35.0 MPa. Calculate the resolved shear stress acting on the (111) slip plane in the [110], [0-11], [10-1] slip directions.
The elevation of water in well A is 300m above sea level and well B is 350m above sea level. The wells are 45m apart. A dye test reveals that the specific discharge between the two wells is about 2.75m/day.
