1.If water is moving at a constant rate through a level conduit andthe pressure is measured as 100 psi at P1 and 90 psi atP2, what is the head loss ( in feet) due to friction?There are no external forces acting on the water. Temperature is60oF
2.The water in a tank is 35 feet deep. Temperature=70oF. What is the gage pressure in psi at the bottom ofthe tank?
3.Calculate the amount of water that will impact a five acre field from 5 inches of rainfall. Express the answer in gallons and cubic meters.
4. A rectangular culvert 4 feet x 6 feet is running full and discharging 3,500 cfm. There is no friction loss. Find the velocity in fps. The culvert empties into a 10 ft wide culvert and the velocity reduces to 0.6 fps. How deep is the water level in the second culvert?
5.Compute the height (h) of the water tank above theground surface to provide a static pressure of 75 psi.
Compute the pressure at a point in a building that is 40 feet abovethe ground surface.
Note: the pressure in a water system will range from 40- 90psi. Compute the range in h corresponding to this range inpressure. Answer in feet
A gas stream with a particulate loading of 20.0g/m^3 is passed through a 70%-efficient cyclone followed by a 95%-efficient ESP. Calculate the overall efficiency of the system.
The mass m, stiffness k, and natural frequency fn of an undamped SDF system are unknown. These properties are to be determined by harmonic excitation tests. at an excitation frequency of 4 Hz, the response tends to increase without bound.
The suspended load exerts a force F = 600 lb at A and bar OA weighs 200 lb. Assume that the bar's weight acts at its midpoint. Determine the tensions in the cables and the reactions at the ball and socket support O.
velocity of water in the nozzle is given by V=2t/(1-.5x/L)^2. L = 4ft. When x=.5L and t=3s what is the local acceleration along the centerline. What is the convective acceleration.
A 40 oF breeze of 10 miles per hour blows over the top of a round open-top water cooling tank which has a bulk temperature of 100 oF. What is the rate of energy in kW that enters into the air
A steel pipe carries an industrial oil under pressure. The steel pipe inside diameter is 36 in, the pressure head on the fluid is 383.0 ft. A)- Find the internal fluid pressure in psi
The column is constructed from high-strength concrete and four A-36 steel reinforcing rods. If it is subjected to an axial force of 37.5 kN , determine the required diameter of each rod so that one-fourth of the load is carried by the concrete
It leaves the pump through a 4-in-diamter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump.
an existing water treatment plant is producing an average flow of 0.5 mgd. due to several limitations the plant only
1. an analysis of dredged sediments from a stormwater retention basin revealed a high concentration in mgkg of the
The rod is made of a-36 steel and has a diameter of .25 in. if the springs are compressed 0.5 in when the temperature of the rod is T=40F, determine the force in the rod when its temperature is T=160 F.
In a falling-head permeability test the initial head of 1.5m dropped to 0.5m in 4 h the diameter of the standpipe being 5mm. The soil specimen was 200mm long by 100mm in diameter.
