1.The bracket ABC can be supported in the eight different ways shown. All connections consist of smooth pins,rollers, or short links. For each case, answer the questions listed in Prob.4.59,and, whenever possible , compute the reactions,assuming that the magnitude of the force P is 100 lb.
2.A pumped storage power plant is to be designed for a flow rate of 6,000 cfs per penstock. The penstocks are 20 ft. in diameter, with a relative roughness of 0.008. The elevation difference between the two reservoirs is 340 ft. The head loss has to be less than 2% of the head available from the pump.
a.) Determine the allowable length of the penstock.
b.) Determine the HP of the pump required to pump the water.

A 5m wide rectangular sluice gate is opened to a height of 1.5m. the upstream water level is 4m and the downstream level os 2m. What is the discharge under the gate.
From the results of an oedometer test on an undisturbed sample of clay taken at a depth of 10 m from the ground surface, the maximum vertical preconsolidation pressure (s'vmax or s'c) was found to be 560 kPa.
The initial velocity of a 15-lb block is given as mv1=15i+15j (ft/s). A force defined by F=250i-250tj (lb) acts on the particle from time t=0 to time t=0.3 s for a total duration of 0.3 s.
The pollutant has a reaction rate coeeficient k of 0.25/day. Assuming is pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.
A cylindrical core, completely saturated with oil up to immobile water saturation, is immersed in water and the measured volume of oil displaced by imbibition of water is 7.5 c.c.
A WTP Operator is trying to size a pump that takes water from a WTPholding tank and sends it to a house on a hill above theplant. The operator's goal is to have 60 psi of waterpressure entering the house. The operator knows that the head loss (major+..
