Leak Detection and Repair

Formula for Air Leak Rate:

Q = (C / P) * sqrt(2 * P * ρ)

Where:

  • Q = Leak rate (cfm)
  • C = Flow coefficient
  • P = Pressure (psi)
  • ρ = Density of air (lb/ft³)

Calculate:




Result: N/A cfm

Pressure Drop Calculation

Formula for Pressure Drop:

ΔP = (Q^2 * L * k) / d^5

Where:

  • ΔP = Pressure drop (psi)
  • Q = Flow rate (cfm)
  • L = Length of pipe (feet)
  • k = Friction factor (dimensionless)
  • d = Diameter of pipe (inches)

Calculate:





Result: N/A psi

Flow Rate Calculation

Formula for Flow Rate:

Q = C * A * sqrt(2 * g * h)

Where:

  • Q = Flow rate (cfm)
  • C = Discharge coefficient (dimensionless)
  • A = Area of orifice (square feet)
  • g = Acceleration due to gravity (32.174 ft/s²)
  • h = Pressure head (feet)

Calculate:




Result: N/A cfm

Cycle Time Calculation

Formula for Cycle Time:

t = L / v

Where:

  • t = Cycle time (seconds)
  • L = Stroke length of the cylinder (inches or feet)
  • v = Velocity of the piston (inches/second or feet/second)

Calculate:



Result: N/A seconds

Force Calculation

Formula for Force Output:

F = P * A

Where:

  • F = Force (lbs)
  • P = Pressure (psi)
  • A = Area of the piston (square inches)

Calculate:



Result: N/A lbs
