7.48 - Correct Answer-How many gallons of water in 1 cubic foot? 62.4 lbs/ft^3 - Correct Answer-Weight of water? Pressure = Force / Area - Correct Answer-Formula for pressure? Water works supply - Correct Answer-What type of water supply is preferred? The size of the system riser - Correct Answer-For a pipe schedule design, the underground supply must be a minimum of? Hose stream demands - Correct Answer-If pumps serve only sprinklers, they are permitted to be sized to provide the flow needed for the sprinkler system without ____? Assessing their impact on the water supply to the pump - Correct Answer-The flow demands for equipment not connected to the pump do no need to be taken into considerations, expect for? Pressure tank size = water capacity + air capacity - Correct Answer-Formula for calculating pressure tank size? Flow available = Flow at test location * [(static pressure - pilot pressure) / (static pressure - residual pressure)]^0.54 - Correct Answer-Water supply available flow formula: h1+(p1/weight of water)+(v1^2/2*g)=h2+(p2/weight of water)+(v2^2/2*g)+hf - Correct Answer-Bernoulli's equation: Q1=Qt/((L1/L2)^.54+1) Q2=Qt/((L2/L1)^.54+1) - Correct Answer-Loop calculation split flow equation with same pipe diameters: Le=L1*(De/D1)^4.87*(Ce/C1)^1.85 Le is new equivalent length L1 is original equivalent length De is pipe diameter of new equivalent length D1 is original pipe diameter Ce is C-factor of new equivalent length C1 is original C-factor Note: make the smaller pipe equivalent to the large pipe - Correct Answer-Loop calculation split flow equation with different pipe diameters: (p1-p2)=.433*(h2-h1) - Correct Answer-Equation for measuring static pressure with differences in height (elevation): Static pressure=friction loss pressure + residual pressure + velocity pressure - Correct Answer-Static pressure equation
