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

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
