Answer:

Explanation:
The phenomenon can be modelled after the Bernoulli's Principle, in which the sum of heads related to pressure and kinetic energy on ground level is equal to the head related to gravity.

The velocity of water delivered by the fire hose is:


The maximum height is cleared in the Bernoulli's equation:



Answer:

Explanation:
Let assume that heating process occurs at constant pressure, the phenomenon is modelled by the use of the First Law of Thermodynamics:

The specific enthalpies are:
