A buried stock-water pipeline conveys water from a water source at Point 1, rises to pass up and over the peak of a hill (Point 2) before falling to Point 3 in the pipeline some distance before a watering point (outlet). Analyse this situation in terms of an ideal fluid flow (i.e. without any losses), if the steady discharge is 0.23 L/s at Point 3 and it is lower than Point 1 by 20 meters. Point 2 has a pressure of 1 meter head. If the diameters for the pipeline at Points 1, 2 and 3 are 0.019, 0.15 and 0.025 meters, respectively, and the pressure at 1 is 150 kPa, what is the elevation at Point 2, and the pressure at Point 3?
Field tests have shown that the Horton equation best describes the composite roughness of the channel. Find the capacity of the main channel and the lateral extent of the floodplains for a 100-year flow of 1590m^3/s.
Use the strain-transformation equations to determine (a) the in-plane principle strains and (b) the maximum in-plane shear strain and average normal strain.
a pipeline terminates in a nozzle of outlet diameter 0.15 m. the free jet from the nozzle is deflected through
An Element of soil (sand) behind a retaining wall is subjected to an increase in vertical stress of 60kPa and an increase in lateral stress of 25 kPa. Determine the increase in vertical and lateral strains,
A 10-min experimental run shows that 75% of a reactant is converted to a product by a zero-order reaction rate. What would be the fraction converted in a half-hour run. Assume the reactor is a batch reactor.
A new concrete mix is being designed to provide adequate compressive strength for concrete blocks. The specification for a particular application calls for the blocks to have a mean compressive strength greater than 1350 kPa.
Consider the rocket on a test stand . The nose of the rocket is fixed. The rocket is of length L, constant EA and constant m, mass per unit length. To investigate longitudinal dynamics, the rocket is modeled using axial elements of equal length.
calculate the cracking moment (resisting moment) for an unreinforcedconcrete beam that is 10 in. wide, 16 in. high. assume normal weight concrete with 3000 psi = f prime sub c. use the internal couple method and check with the flexure formula.
