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.
In Chlorine disinfection (3-log reduction in Giardia- Cysts), determine the water pH for a contact time of 90 minutes using a chlorine concentration of 2 mg/L at 20 degrees C
Nitrate concentrations are often recorded in units of NO3--N/L to be compared with other nitrogen constituents. Near three rural wells nitrate concentrations were reported as 0.25 mg
Raw primary sludge at a solids concentration of 3% is mixed with waste activated sludge at a solids concentration of 6,000 ppm. The flows are 20 and 25 gal/min, respectively. What is the resulting solids concentration?
A soil proposed for a compacted fill contains 38% fines and 62% coarse materials by dry weight. when the coars fraction has w=2.0%, its affinity of water is completely satisfied( that is,it is saturated but surface dry).
Design a broad crested weir for a laboratory flume with a width of 1.25 ft. The discharge range is 0.1 to 1.0 cfs. The maximum approach flow depth is 18 inches. Determine the height of the weir P and the weir length l in the flow direction. Assume cv..
Consider a wind turbine at elevation of 7000 ft. The air pressure is taken to be 80kPa and the mean annual temperature is 2 degrees Celsius. What are the specific mechanical energy and power available
given f(x) = -2x^6 - 1.5x^4 + 10x +2. use a root location technique to determine the maximum of this function. perform iterations until the approximate relative error falls below 5%.
The United States Environmental Protection Agency (EPA) has published the following data for municipal solid waste generation (in millions of tons).
A sample of moist soil has a volume of 40.5 cc mass weight of 59.2 gms. After drying it has a mass weight of 48.3 grams. The specific gravity of the solids are 2.68.
For two 0.2 m long rotating concentric cylinders, the velocity distribution is given by u(r) = 0.4/r - 1000r m/s. If the diameters are 2 cm and 4 cm, respectively, calculate the fluid viscosity if the torque on the inner cylinder is measured to be 0...
The owner wish to achieve an initial acceleration from rest of 15 ft/s^2 on a level paved surface. What is the maximum coefficient of road adhesion needed to achieve this acceleration
a newly designed car has a 9.2 ft wheelbase, is rear wheel drive, and has a center of gravity 18 inches above the the road and 4.3 ft behind the front axle. the car weighs 2450 lb, the mechanical effciency of the drivetrain is 90%, and the wheel r..
