An engineer is making an estimate for a homeowner. This owner has a small stream (Q=1.4 cfs, T=40°F) that is located at an elevation H=34 ft above the owners’ residence. The owner is proposing to dam stream, diverting the flow through a pipe (penstock). This flow will spin a hydraulic turbine, which in turn willdrive a generator to produce electrical power. Estimate the maximum power in kilowatts that can be generated if there is no head loss and both the turbine and generator are 100% efficient. Also, estimate the power if the head loss is 5.5 ft, turbine is 70% efficient, and the generator is 90% efficient. (20 pts

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
