If direct runoff hydrgraph derived from a unit hydrograph of a catchment (drainage area = 50 acre) is 120 acre-ft, back calculate the rainfall amount. Assume total abstraction in the area is 50%.
Determine the height "h" on the wall to which the firefighter can project water from the hose...and the speed of the water at the nozzle is v= 55ft/s. The firefighter is holding the hose 3.5 ft from the ground and the wall is located 15ft from the..
describe the measurements that would have to be taken and the equations that would have to be used to determine G23, V32, and E2 for a specially orthotropic transversely isotropic material from a single tensile test.
A train 552 m long is moving on a straight track with a speed of 88.5 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 13.7 km/h.
the pin at B is attached to member ABC and can slide freely along the slot cut in the fixed plate. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when.
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
Estimate the required surface area (A), and the diameter and the depth of the tank.
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..
What is work? Why is it path dependant? Derive the expression for reversible work from a closed system containing a simple compressible substance.
The aluminum bar has an electrical coil imbedded in it, so that known amounts of heat can be transferred to it. Aluminum has a specific gravity of 2.70 and a specific internal energy given by the formulaU (kJ/kg)=0.94T(C).
given that E for the tube material is 70 GN/m2 and the stool legs are 75cm long, how much will each leg shorten under the applied compressive load (take g = 9.8m/s2)
To provide knowledge and practice AutoCAD software package for engineering activities.
Include immediate and consolidation settlements, but ignore secondary compression. In your calculation, use three sublayers with thicknesses of 4 ft, 8 ft and 16 ft for the top, middle and bottom layers. Ignore any settlement caused by the dense s..
