In an industrial cooling process, water is circulated through a system. If the water is pumped with a speed of 0.45 m/s under a pressure of 400 torr from the first floor through a 6.0-cm diameter pipe, what will be the pressure on the next floor 4.0 m above in a pipe with a diameter of 2.0 cm?

In an industrial cooling process, water is circulated through a system.

If the water is pumped with a speed of($v}_{1}=0.45\frac{m}{s$ )

under a pressure of ($P}_{1$ = 400 torr) from the first floor througha($D}_{1$ = 6.0cm) diameter pipe,

Let '$P}_{2$ ' be the pressure on the next floor ( h = 4.0 m ) above in a pipe with adiameter of ($D}_{2$ = 2.0 cm)

Density of water =$1000k\frac{g}{{m}^{3}}$

From the equation of continuity we have

The rate is$A}_{1}{v}_{1}={A}_{2}{v}_{2$

Or,$v}_{2}={A}_{1}\frac{{v}_{1}}{{A}_{2}$

Or,$v}_{2}={\left(\frac{{D}_{1}}{{D}_{2}}\right)}^{2}{v}_{1$

Apply; Bernoulli's Theorem

${P}_{1}+\left(\frac{1}{2}\right){v}_{1}^{2}+0={P}_{2}+\left(\frac{1}{2}\right)\cdot {v}_{2}^{2}+h\cdot g$

Put the above given values in the above expression , to get'$P}_{2$ '

Four very long, current-carrying wires in the same plane intersect to form a square with side lengths of 45.0 cm, as shown in the figure blelow. The currents running through the wires are 8.0 A, 20.0 A, 10.0 A, and I.

Part A

Find the magnitude of the current I that will make the magnetic field at the center of the square equal to zero.

Part B

What is the direction of the current I (up or down)?
