Dear All,
My new offer for all of you regarding to Knowledge Sharing is a spreadsheet called "Thumb Rules For Process Engineers" and covers the following subjects:
PIPING PRESSURE DROP : For Raynold's no 2100 to 106
EQUIVALENT LENGHTS for Pressure drop in the system
MAXIMUM ALLOWABLE FLOW OF STEAM THROUGH PIPE 41, 12 & 2" only
ALLOWABLE VELOCITIES FOR PROCESS FLUIDS
SONIC VELOCITY CALCULATION
PERMANENT HEAD LOSS THROUGH ORIFICE
VENTURI Pressure Drop
FLOW RECTANGULAR WEIR
CONTROL VALVE SIZING
RELIEF VALVE SIZING FOR LIQUID EXPANSION
STORAGE VESSEL VOLUMES
NPSH
Pressure Drop in Pipeline
TUBESIDE PRESSURE DROP IN SHELL & TUBE HEAT EXCHANGER
MOTORS kVA
MOTORS AMPS ETIMATE
CENTRIFUGAL COMPRESSOR HP
CENTRIFUGAL COMPRESSOR HEAD
TEMPERATURE RISE IN COMPRESSION

TUBESIDE PRESSURE DROP IN AIR COOLED HEAT EXCHANGER
MOTOR HP OUTPUT
MOTOR TORQUE
GAS EXPANDERS : AVAILABLE ENERGY
POWER FACTOR
SELECTION OF TYPE OF VACUUM EQUIPMENT
