1.Manometers are often incline. Why? if a manometer incline at 45 degrees containing a fluid with specific gravity of a 2.0 using it to measure the pressure in a system, and the fluid levels rise 30 inches. What is the pressure in the system in Lbf/In^2 and H2O? As soon as Miss spirit pressure is 29.9 inches Hg.
2.Shaquille O Neal, who is listed as 7`1" tall is out of the NBA Playoffs and so has time to visit is pool. If he stands vertically in the water, completely submerged, determine the difference between the pressure is acting at his head and at his toes, in Lbf/in^2.
A drop of water forms under a solid surface. assume the drop has the shape of a hemisphere just before seperating. find an expression for the diameter, D
Compare the size of a CMFR (completly mixed flow reactor) and PFR (plug flow reactor) to achieve 50 percent removal of a contaminant, given a flow rate of 10^4 m^3/d and a first-order rate constant of -0.4/hr. Repeat for 99 percent removal.
Due to a leak in Pump Station 1,the Alaska pipeline is shut down briefly.The pipe line is half full.Assume the pipe is welded horizontally at its midpoint.What is the tensile force on the weld per foot? Assume Ø=40”and ?oil=53.55lb/ft3.
Determine the maximum and minimum stress intensities in the section.
Determine the shear stress in a 25 × 50 cm rectangular section if the shear force is 20 KN and torsional moment is 10 KN m at service loads. Assume M20 mix and 0.75% tension reinforcement at an effective cover of 50 mm.
determine the velocity of the 30 kg block A if two block are released from rest and the 20 kg block B moves 0.6 m up the incline. the coefficient of kinetic friction between both blocks and the inclined plane is 0.10
What power must the pump supply to the system to pump the oil from the lower reservoir to the upper reservoir at a rate of .2 m^3/s. Sketch the HGL and the EGL for the system.
Below a discharge from a wasterwater treament plant , an 8.6km stream has a reoxygenation constant of .4 d^-1, a velocity of .15m/s, a dissolved oxygen concentration of 6mg/L, and an ultimate demand of 25mg/L.
Describe the equation for discharging a water tank. Use: H= 2m, A_s= 1m^2, density water= 1000kg/m^3, K = 1kg hr^-1 m^-1/2 Mass flow in = 0 and mass flow out given by, Mass flow out = K z^1/2.
