Novay_Z [31]

Answer:

Equal

Explanation:

Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.

In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.

Oil (specific gravity of 0.80 and a viscosity of 0.000042 lbf/ft2) at a temperature of 80 F flows through two separate pipes 10
Elenna [48]

Answer:

The velocity of flow in 10in pipe is 4.16 ft/s.

Explanation:

Given that

Specific gravity = 0.8

Viscosity =0.00042lbf/ft^2

For pipe 1

V_1=6 ft/s,d_1=12\ in

For pipe 1

V_2,d_1=10\ in

If we assume that flow in the both pipe is laminar

For laminar flow through circular pipe

\dfrac{\Delta P}{L}=\dfrac{32V\mu }{d^2}

So same pressure drop we can say that

\dfrac{V_1 }{d^2_1}=\dfrac{V_2}{d^2_2}

\dfrac{6}{12^2}=\dfrac{V_2}{10^2}

V_2=4.16 ft/s

So the velocity of flow in 10in pipe is 4.16 ft/s.
