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?
Determine the excess pressure inside an 0.5-in-diameter soap bubble floating in air, given the surface tension of the soap solution is 0.0035 lb/ft.
Consider a portion of the sheet that is 2 in.x 2 in and 0.04 in. thick when the loads are acting. Determine the in-plane x-dimension of this portion of the sheet if these loads are released
Draw a plan of a typical strip mine showing all operational features and equipment and why is the working slope of an open pit usually much flatter than the final slope?
For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant
The settlement analysis for a proposed structure indicates that 6cm of settlement will occur in 4 yr and that the ultimate total settlement will be about 25cm. estimate (a) the ultimate total settlement and ..
the student strikes the sign at a speed of 25 mi/h. if the student was traveling at 55 mi/h when the sign was first spotted, what was the students associated perception/ reaction time
A pressure gage at elevation 4.8 m on the side of a storage tank containing oil reads 34.7 kPa.Another gage at elevation 2.2 m reads 57.5 kPa. Compute the specific weight, density, and specific gravity of the oil.
The design parameters are: • Q = 65 m3/d, • Wetland area (A) = 0.23 hectares (2,300 m2) (including the safety factor), • Aspect ratio = 8:1 • Average water depth (d) = 0.5 m • Bed slope = 1% (0.01 m/m) Given that the Manning's resistance factor
