A 1.5 m3 tank contains 500 kg of liquid water in equilibrium with pure water vapor, which fills the remainder of the tank. The t
emperature and pressure are 100°C and 101.33 kPa. From a water line at a constant temperature of 70°C and a constant pres- sure somewhat above 101.33 kPa, 750 kg of liquid is bled into the tank. If the temper- ature and pressure in the tank are not to change as a result of the process, how much energy as heat must be transferred to the tank?

Hi!
The perpendicular distance 2.4cm, is much less than the distance to both endpoints of the wire, which is aprox 1m. Then the edge effect is negligible at this field point, and we can aproximate the wire as infinitely long.
The electric filed of an infinitely long wire is easy to calculate. Let's call z the axis along the wire. Because of its simmetry (translational and rotational), the electric field E must point in the radial direction, and it cannot depende on coordinate z. To calculate the field Gauss law is used, as seen in the image, with a cylindrical gaussian surface. The result is:
Then the electric field at the point of interest is estimated as:
