2 answers:
Answer:
Explanation:
We want to find the distance the jet travels. Distance can be found by multiplying the speed by the time.
The speed is 100 meters per second.
The time is 10 seconds.
Substitute the values into the formula.
Multiply. Note that the seconds, or "s" will cancel each other out.

Explanation:
Formula for steady flow energy equation for the flow of fluid is as follows.
Now, we will substitute 0 for both and
, 0 for w, 334.9 kJ/kg for
, 2726.5 kJ/kg for
, 5 m/s for
and 220 m/s for
.
Putting the given values into the above formula as follows.
q = 6597.711 kJ
Thus, we can conclude that heat transferred through the coil per unit mass of water is 6597.711 kJ.
