(49g) (50g) Density of water
HP49-50G
Density of water calculation.
According to Tanaka's work.

For boiling temperature of water = f(altitude, air.temp),
see more recent directory
water.doc posted on August 20th 2021.


3 Arguments to be given:
- temperature in Celsius
- pressure in Pascals
- 1 or 0
(1 for tap water;
0 for pure water).

Example
10 (degrees Celsius)
101325 (normal pressure)
0 (for pure water, not tap water)

Result
:t.C: 10
Tongue.PA: 101325
:Pure H²O, w/o air:
999.702701629 :
Pure H²O, 100% air:
999.699149629

Code
\<< "3 Arg:
\[] temp [\^oC]
\[] pressure [PA]
\[] 1/0
[1 for tap water]
[0 for pure water]

According to Tanaka
0 < t.C < 40 \^oC
