pub fn px(p: f64, x: f64, o_id: i32) -> f64Expand description
px(p,x,o_id) - the propertry of o_id (thermodynamic)
Examples
use if97::*;
let p: f64 = 0.1;
let x: f64 = 0.0; // x= 0.0 saturation water ,x=1.0 saturation steam
let t: f64 = px(p, x, OT);
let h: f64 = px(p, x, OH);
println!("px: p={p:.6} x={x:.6} t={t:.6} h={h:.6}");
