Input Data for Hydraulic Design

The following is a summary of input data to be prepared before the hydraulic design

1. Operational Data

-Service for identification
-Fluid name for identification
-Flow rate(s) of liquid and/or vapor
-Temperature
-Pressure
-Physical Properties

a. Liquid service:    Density,viscosity,vapor pressure,critical pressure,spgr@15oC
b. Vapor service:    Density,viscosity,molecular weight,Cp/Cv,Z-factor
c. Two-phase flow:Densities and viscosities for both liquid and vapor, surface tension

2. Construction Data

-Line class
-Elevation at inlet and outlet of piping system
-Distance between source and destination, sum  of XYZ coordinate length
-Instruments, types and quantities
-Valves and fittings, types and quantities, if available
-Control valves
-Pumps, compressors, and blowers

3. Design Requirement

-Marginal head of the pump NPSH available, if any
-Overdesign %: specification of the design flow rate, if any
-Turndown %: specification of the minimum flow rate, if any

4. Output from the Design

-Final Line size
-Pressure Balance
-Equipment Elevation
