A seamless-tube water pipe with an inside diameter of 250 mm runs from a reservoir to a small nearby town.
a) Calculate the pressure p and the force T per linear mm along the (imaginary) longitudinal seam in the pipe at a point that is 100 metres below the open (free) water surface of the reservoir.
b) If the wall thickness is 8 mm and the allowable tensile stress is 80 MPa, what maximum head h may this pipe safely withstand?
write a c++ code for two classes one being automobile and one being motorcycle both being the base class then at least one derived class from each
A river is 6m deep. The riverbed material has a saturated unit weight of 19.5kN/m3. What is the effective vertical stress 12m below the water surface?
A composite price index for the cost of vegetarian foods called eggs, artichokes, and tofu (EAT) was 330 ten years ago and has averaged an annual increase of 12% since. Calculate the current value of the index.
A water jet of diameter 2 inches and speed of v=60 ft/s is filling a tank at a 70 degree angle. The tank has a mass of 25 lbm and contains 6 gallons of water. The water temperature is 70 degrees F.
Now, knowing ?hp or hl in the 1000’ parallel section, find the single-pipe diameter equivalent to two 12” dia ones. Assume high Rh, so Fig 9.11 applies.
The interior height of the cone is 3.60 in. The cone has an exterior radius of 1.25 in and an interior radius of 1.10 in. The scoop of ice cream sits on the cone's interior radius and extends into the cone some distance.
Flow velocity is given by the function v= -5i +3j . Find the equation for the velocity potential, and the stream function ?. Sketch the equipotential line going through the origin.
A buried horizontal concrete pipe (n=0.012) of unknown length needs to be replaces. the length is not known because the original plans for the pipeline route have been lost.
Some distance downstream, the velocity profile can be (very) roughly approximated by a region inside the wake with u = U/2 and an exterior region with u = 3U/2.
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
A spring is used to stop a 50 kg package which is moving down a 20 degree incline. the spring has a constant of 30kN/m and is held by cables so that it is initally compressed 50mm
Do you believe it is plausible that the blocks do not meet the specification, or are you convinced that the blocks meet specification? Explain your reasoning.
