A 0.9 efficient Francis turbine produces 200 MW with a speed of 150 rpm. The blade height is 1.0 m, and the inlet radius of the rotor is 7.0 m. The flow exits the turbine in a radial direction. (a) If the angle between the radial direction and the absolute velocity at the inlet is 30o, determine the volumetric flow rate. (b) What is the change in head across the turbine?
A particle which moves with curvilinear motion has coordinates in meters which vary with time t in seconds according to x = 3.3t2 + 3.1t - 5.3 and y = 5.1t - 4.0. Determine the coordinates of the center of curvature C at time t = 1.9 s.

A dry quartz sand has a unit weight of 100 pcf. What is the soil's unit weight when the degree of saturation is 75% if Gs = 2.66
A large residence consumes 3705 kWh of electrical energy over a billing period. Determine the total charge for the billing period based on the rate schedule provided. The margin of error is $0.5
Water with a static pressure of 1.96kN/M 2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M 2 . How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/se..
Draw the shearing force diagram and the moment diagram of the following problem. The beam is indeterminate. You need to integrate the moment twice to get a formula for the deflection v(x).
Write the mass balance equation for a plug flow with a second order decaying substance,C. Solve for the steady state concentration of C as a function of the second order rate constant k, longitudinal distance x, mean velocity u, and the concentrat..
Presedimentation can reduce the suspended solids concentration of raw river water from 500 mg/L to 200 mg/L. How many pounds of dry solids does this represent per million gallons?
The cross sectional dimensions of a 4-ft-long wood member at 30% moisture content is 1.5 in. x 7.5 in., and its weight is 11 lb. At oven-dry condition, its dimensions and weight are 1.35 in x 6.8 in., and 10.2, respectively. What is its specific g..
