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
