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
After falling from rest from a height of 32 m, a 0.45 kg ball rebounds upward, reaching a height of 22 m. If the contact between ball and ground lasted 1.5 ms, what average force was exerted on the ball?
Suppose that in a senior college class of 500 students it is found that 210 smoke, 258 drink alcoholic beverages, 216 eat between meals, 122 smoke and drink alcoholic beverages, 83 eat between meals and drink alcoholic beverages
The bar is prevented from rotating by the two pegsA and B fixed to the plate. Determine the acceleration a of the plate for which no force is exerted on the bar by either peg A or B.
At point D, Fred measured the distance to point E, the final point, to be 405.27 ft. The noon whistle sounded (you may have to have a little "small town" in you to appreciate the noon whistle), so they left in a hurry without measuring the angle C..
For the loading sown, use double integration method to determine: the equation of the elastic curve for the cantilever beam, the deflection at the free end and the slope at the free end.
If the pipe is designed with a safety factor of two [i.e. the maximum stress in the field must be less than half the rated yield stress], what is the maximum depth that can be safely reached for drilling.
the behaviour of structural materials using comparative statement when they are formed into structural
Iron and vanadium both have the BCC crystal structure, and V forms a substitutional solid structure in Fe for concentrations up to approximately 20 wt% V at room temperature.
Hardness is sum of all divalent cations (meaning all species with a positive charge of 2) in a water sample. Magnesium (Mg2+) and calcium (Ca2+) are the most common divalent cations that contribute to hardness.
An open test tube at 293 K is filled at the bottom with 12.1 cm of Hg and 5.6 cm of water is placed above the mercury. Calculate the pressure at the bottom of the test tube if the atmospheric pressure is 756 mm Hg.
A 8 inch polyethylene pipe has a flow rate of 1000 gallons/minute with a linear length of 10000ft. Starting at elevation 200ft then ends at 600ft elevation. Initial pressure is 40 psi. find the friction and the head loss.
n ideal gas in 1.50 gallon container is at a temperature of 125 degrees Celsius and of 2.5 atmospheres. If the gas is oxygen (formula: O_2, molecular weight = 32 grams per mole), what is the amount of gas in the container in units of grams
