Pipe Pressure Drop and Pump Sizing Calculator
Wired White v1 Calculate pipe pressure drop, pump head, shaft power and NPSHa with Darcy–Weisbach. Compare system and pump curves using Colebrook or Swamee–Jain friction factors.
Psychrometric Chart Calculator: Air States and HVAC Processes
Wired White v1 Solve moist-air states from two independent properties and plot HVAC processes. Calculate coil duty, air mixing, humidification and condensate at your site pressure.
Junction temperature of a power semiconductor
Wired White v1 Estimate steady-state junction, case, and sink temperatures and a single-pulse junction rise from a four-term Foster model.
