Reservoir A supplies water to a nozzle having diameter of 80 mm which discharge water 40 m below the reservoir water level at a velocity of 24 m/s. Determine the horsepower produced by the jet. a.

Solution:
1. Select an A992 structural tee (WT) for the top chord of the welded roof truss shown below. All truss connections are constructed with longitudinal plus transverse welds. Assume a connection length of 12 inches. The spacing of the trusses is 15 feet. Design for the loads shown Snow: 20 PSF on horizontally projected area. Roof deck: 12 PSF MC8x8.5 purlins Truss weight: 1000 LB (estimated; assume uniformly distributed horizontally)……
2. The tension member shown is ax 5 A242 steel plate. It is connected to a 5-inch thick A242 steel gauss plate, with 7-inch diameter bolts, as shown below. Determine the nominal tensile strength of the connection including the limit states of yield, fracture, and block shear. What is the reduced nominal strength of the connection?
Calculating the nominal strength in yielding:
Pn =FyAg
Here, nominal strength is Pn, yield strength is Fy, and gross area of section is Ag.
Substitute 50 ksi for Fy, and 4.79 in2 for Ag
Pn = 50 x 4.79 ksi in² = 239.5 kips
Calculating the diameter of hole:
dh = diameter of bolt + side clearance
Here, diameter of hole is dh
Substitute 3/4 in. for diameter of bolt, and in. for side clearance:...
