Title "Boiling point of water as a function of pressure";
Variable Pressure; // Pressure in vessel in pounds per square inch
Variable Temp; // Temperature in degrees Fahrenheit
Parameter a = 1700;
Parameter b = -3200;
Function Temp = b / log(Pressure/a) - 459.7; // Clapeyron's equation
Plot xlabel="Pressure (PSI)",ylabel="Temperature (degrees F.)";
Confidence 90; // Print 90% confidence intervals
