* A barometer filed with non-toxic glycerin is used to measure standard sea level atmospheric pressure. neglecting the effect vapor pressure and surface tension. calculate the atmospheric pressure head.
* correct the result of problem above for the effect of vapor pressure and surface tension. assume that the bore of the tube is 10mm.
determine by trigonometry (a) the required tensoin T2 in the left hand portion if the R of the force exerted by the cable at A is to be vertical, (b) the corresponding magnitude of R.
Estimate the chronic daily intake of 1,1,1-trichloro ethane from exposure to a city water supply that contains a 1,1,1-trichloroethane concentration equal to the drinking water standard of 0.2 mg/L.
A company borrowes $25000 at an interest rate of a nominal 16% per year compounded quarterly. The company desires to repay the loan in 36 equal quartely payments, with the first payment starting three months from now.
Air at 200 kPa and 950 K enters an adiabatic nozzle at low velocity and is discharged at a pressure of 80 kPa. If the isentropic efficiency of the nozzle is 92%, determine the temperature and velocity of the air at the exit.
Knowing that its speed continues to increase at the same rate until it reaches 100 km/h at point C, 1) determine the speed at point B, and 2) the magnitude of the total acceleration when t = 20 seconds.
Only the inner cylinder is rotating. THe velocity distribution is given by V(r)=1000r-0.4/r [m/s]. If the diameters of the cylinders are 3 cm and 5 cm, respectively
A small city is evaluating disinfection requirements for their drinking water plant. With an average flow of 5 MGD and a peak flow of 9 MGD, determine the controlling CT factor (virus or giardia) when the water temperature is 23 degrees C.
The 75 lb block is released from rest 5 ft above the plate. Determine the compression of each spring when the block momentarily comes to rest after striking the plate.
Evaluate company performance in relation to GRI standards and comment on Stigler's theory.
Alkaloids are chemical compounds containing nitrogen that can be produced by plant cells. In an experiment, an insulated closed vessel 1.673 m3 in volume was injected with a dilute water solution containing two alkaloids: ajmalicine and serpentine..
