Charles' First Law - (ANSWER)Volume1 / Pressure1 = Volume2 / Pressure2
Charles' Second Law - (ANSWER)Pressure1 / Temperature1 = Pressure2 / Temperature2
Boyle's Law - (ANSWER)Pressure1 x Volume1 = Pressure2 x Volume2
General Gas Law - (ANSWER)(Pres1 x Vol1)/ Temp1 = (Pres2 x Vol2)/Temp2
Formula for Levers - (ANSWER)Resistance x DistanceR = Effort x DistanceE
Formula for Inclined Planes - (ANSWER)Force x Length = Resistance x Height
Formula for Wheel & Axel - (ANSWER)Force x DistanceF = Resistance x DistanceR
Torque - (ANSWER)Force x Radius
Safe Working Pressure of a Riveted Boiler (SWP) - (ANSWER)(Area of Staybolt x Stress
Constant of Staybolt) ÷ Area Covered by Staybolt or = (a x C) ÷ A
Area Covered by Staybolt - (ANSWER)= Pitch x Pitch
, Longitudinal Stress - (ANSWER)(P x D x L) / 2t
P = Pressure
D = Diameter
L = Length
t = thickness of steel
Boiler Heating Surface (tubes) = - (ANSWER)= C x L x #
C = Circumference of tubes
L = Length of tubes
# = Number of tubes
HS = π x Diameter x Length x Number of Tubes
Watts per Boiler Horsepower - (ANSWER)746 Watts
Horsepower formula - (ANSWER)= ft-lb/min ÷ 33000 ft-lb/min
ft-lb formula for a pump - (ANSWER)= gpm x 8.33 x head (ft)
Factor of Evaporation (FE) = - (ANSWER)= [Hs - (tfw-32)] ÷ 970.3
Hs = Enthalpy of steam
tfw = temperature of feed water
Latent Heat of Vaporization for Water - (ANSWER)970.3 Btu/lb
Latent Heat of Fusion for Water - (ANSWER)144 Btu/lb
1 Boiler Horsepower = x lbs of steam generator per hour - (ANSWER)34.5 lbs/hr
