pocketPipe: a handy tool for your pipe design and sizing

Pipe sizing and pipe friction loss calculations have never been easy. Not anymore! With pocketPipe (Pipe Sizer), you can do your pipe design and sizing at anytime, anywhere...

Aim: creating a mobile design environment (ShowMe!) for the practising engineers & designers in today's mobile world.

Results: Instant solutions at your fingertips.

Highlights:

- chilled, condenser & hot water calculations (Find capacity, flowrate, dT)

- general purpose pipe sizing + pipe frictional loss rate ( Hazen-Williams or Darcy-Weisbach)

- cold pipe insulation thickness and heat gain calculation

- "save-to-file" function for printing

- in SI units only

Pipe Sizer: design explained . . .

Pipe Sizer employs 2 options for pipe friction loss calculation, i.e., Hazen-Williams equation or Darcy-Weisbach equation . Darcy-Weisbach method is generally considered more accurate than Hazen-Williams method. However, Hazen-Williams method is very popular since its friction coefficient, C, is not a function of velocity or pipe diameter. It is to note that Hazen-Williams equation is only valid for water at temperature 4 - 25 ^{o}C (40 -75 ^{o}F).

You can choose water density and pipe materials with built-in database.

Darcy friction factor, f, is solved by Serghide's explicit equation - an approximation of the implicit Colebrook-White equation. Serghide's solution closely mirrors Colebrook's implicit solution within 0.0031%.

Note: Pipe Sizer does not calculate minor (valve and fitting) loss.

For full pipe & fittings frictional loss (pressure drop) calculations,

(a) see Pipe_f.Loss program using Darcy equation and Hooper 2K method for a single pipe calculation.

(b) see ePF Loop Pdrop program for multiple series pipes and a single loop ring main network using Hardy cross method, Hazen-Williams equation, Darcy-Weisbach formula, equivalent length Le method and resistance coefficient K method.
