fuel pressure and boiling

[CHAN WEN YEN]

I think that the pressure necessary to prevent fuel from boiling can be 
calculated aproximately using the following formula:

	ln(P) = -H/8.314 * (1/TO - 1/TB)

	P = minimum necessary pressure (in pascals)
	H = heat of vaporization of the fuel (joules per mole)
	TO = expected operating temperature
	TB = normal boiling point (in kelvin)

	8.314 is the gas constant

The formula assumes ideal gas behaviour and a constant H. A large FOS 
should probably be used.
