"This program, designed for the HP-41CV calculator, will calculate the bore required for an orifice plate for a given rate of flow, or the flow rate for a given bore size, when the following variables are entered into the program:
Flow rate (lb/hr), Flowing temperature (°F), Flowing specific gravity (dimensionless), Differential pressure range (in. of water), Pipe inside diameter (in), Absolute viscosity (centipoises);
Program calculates beta ratio (dimensionless) and orifice bore (in.).
If an even-sized bore is required:
Required orifice bore (in);
Program calculates beta ratio (dimensionless) and new flow rate (lb/hr)."

BEST!
