An 8-in-diameter pipeline (f=0.028) 500 ft long discharges a 3-in-diameter water jet into the atmosphere at a point that is 250 ft below the water surface at intake. The entrance to the pipe is reentrant, with ke = 0.9, and the nozzle loss coefficient is 0.045. Find the flow rate and the pressure head at the base of (entrance to) the nozzle.
A long wide rectangular channel carries a steady flow rate of 35 m2s-1 (flow per unit width) and passes through an abrupt change in slope from 0.005 (upstream of the change) to 0.003 (downstream).
A ladder is supported by a horizontal floor and a vertical wall. Is 15 feet long and weighs 50 lbs, with the weight concentrated at its midlength. The ladder supports a person weighing 180 lbs.
For a 30ft simply supported beam, there is a uniform load of 1.5 k/ft. along the length and two point loads of 20 kips each spaced at (from x=0 to x=30ft left to right) x=10ft and x= 20 ft.
A 40 oF breeze of 10 miles per hour blows over the top of a round open-top water cooling tank which has a bulk temperature of 100 oF. What is the rate of energy in kW that enters into the air What type of heat transfer mechanism is employed in thi..
The Earth's surface creates a boundary layer in the atmosphere. The velocity profile near the surface can be expressed as a power law, u = a * y n, where the constants a and n depend on the roughness of the surface.
The blue plane supporting the roller lis parallel to the xy plane. Force P=600N loads the plate at C. Compute the reaction components that hinge A and roller B exert on the triangular plate.

A trapezoidal channel has a bed width of 3.5 m and a side slope of 30 degrees from the horizontal. Determine the critical depth and the critical velocity for a flow of 22 cubic meters per second.
If the max load is applied to the cylinder (6"x12") or (150x300mm) up to P=500 kips, what would be the compressive strength of concrete for (a) cylinder, (b) 150mm cube, and (c) 200mm cube.
