14. The turbine in the City of Tacoma Power Plant (see Fig. 120) uses a head of 415 ft. 145 cu. ft. a second pass through the turbine. Calculate the horse-power.
15. In problem 14, what is the water pressure per square inch at the turbine?
16. The power plant mentioned in problem 13 develops 6000 kw. What is the efficiency?
Review Outline: Work and Energy
Work; how measured, units, foot-pound, kilogram meter, erg.
Energy; how measured, units, potential, P.E. = w × h, or f × s. Kinetic = (wv2)/(2g).
Power; how measured, units, horse power, watt, 5 forms of energy, conservation. H.p. = (lbs. × ft.)/(550 × sec.).
Machines; 6 simple forms, 2 groups, advantages, uses, Law: W × Dw = F × Df.
Lever; moments, mechanical advantage, uses and applications.
Wheel and Axle and Pulley; common applications, mechanical advantage.
