Some General Pump Theory

BERNOULLI’S THEOREM
• The Bernoulli equation is a special statement of the general energy equation
• Work added to the system is referred to as pump head (hP)
• Losses from the system are referred to as head loss (hL)
• Pressure (lbf/in2) is a form of work
• Strictly Mechanical Energy so we get the equation:
P1 + PE1 + KE1 + WK = PE2 + KE2 + WKFRIC + P2

Z1 + (P1/) + (V12/2g) = Z2 + (P2/) + (V2
2/2g) + hP - hL
Z : Elevation (ft)P : Pressure (lb/ft2)
: Density (lb/ft3)V : Velocity (ft/sec)g : acceleration (32.2 ft/sec2)
Hp: pump head (ft) HL: Head Loss (ft) = f(L/D)(V2/2Zg) where f : friction factor L: Length D: Diameter

THE CONCEPT OF “HEAD”
• The vertical difference between 2 levels of liquid
– Use FT to measure the pressure exerted by a body of liquid in term of weight
• Head α Pressure α Energy
• Velocity Head
– The distance a liquid would have to fall for a given V
– Hv = V12/2g
• Friction Head
– Hl= f(L/D)(V2/2Zg) where
• f : friction factor
• L: Length
• D: Diameter

• Head required to impart velocity to a liquid
• Equivalent to the vertical distance through which the liquid would have to fall to acquire the same velocity
• Equal to V2 / 2g

Friction Head
• The force or pressure required to overcome friction is obtained at the expense of the static pressure head
• Unlike velocity head, friction head cannot be “recovered” or reconverted to static pressure head
• Thermal energy is usually wasted, therefore resulting in a head loss from the system
