• Friction Calculator
    Compute friction force from normal force and coefficient of friction. Enter normal force (N) and coefficient (μ) to get F = μN instantly in newtons.
  • Gas Line Calculator
    Enter total BTU, pipe length (feet), and pressure (inches water column) to get the recommended gas pipe size and estimated flow rate.
  • Viscosity Index Calculator
    Calculate Viscosity Index easily with kinematic viscosity values at 40°C and 100°C. Determine oil performance and viscosity-temperature relationship for efficient lubricant analysis and selection.
