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.

The three resistances are connected in series, their equivalent is equal to the addition of all the resistances. The unknown value of resistance is 1.74 ohm.
<h3>What is resistance?</h3>The resistance is the opposition offered to the flow of current.
Given the value of resistance R₁ is 1 ohm, R₂ is 68 ohm and R₃ is R.
The total current flowing through the battery of voltage 24 V is 0.20 Amperes.
From the ohms law, The equivalent resistance is
= Voltage / Current
The equivalent resistance is
= R₁+ R₂+R₃
24 / 0.20 = 1+68+R
R = 1.74 ohm
The unknown value of resistance is 1.74 ohm.
