The head loss in a turbulent flow in a pipe varies Approximant as square of velocity • Direct as the velocity • Invers as square
Eddi Din [679]

Answer:

Head loss in turbulent flow is varying as square of velocity.

Explanation:

As we know that head loss in turbulent flow given as

h_F=\dfrac{FLV^2}{2gD}

Where

F is the friction factor.

L is the length of pipe

V is the flow velocity

D is the diameter of pipe.

So from above equation we can say that

h_F\alpha V^2

It means that head loss in turbulent flow is varying as square of velocity.

We know that loss in flow are of two types

1.Major loss :Due to surface property of pipe

2.Minor loss :Due to change in momentum of fluid.

Which statement justifies that phosphine (PH3) is a polar molecule?
lorasvet [3.4K]
The P-H bond is polar and the molecule is asymmetric.

Non-polar bonds cannot produce polar molecules and symmetric bonds result in even distribution of charge, so no net charge is observed.

Conductors have(blank) <br> resistance.<br><br> Moderate. <br> Very High. <br> Very low.
Flura [38]

Answer:

<em>The correct option is C) Very low</em>

Explanation:

In physics, resistance can be described as the opposition to the flow of current or the flow of electrons. Conductors are known to be materials which can conduct electricity. Hence, conductivity and resistance are opposite to each other. Good conductors will have very little or no resistance and will have enhanced conductivity. On the contrary, insulators are materials which will have more resistance and they cannot conduct electricity as efficiently.

Onsider the reaction below.
mamaluj [8]

Answer:

3.14 moles of hydrogen are produced

Explanation:

This is because for every 1 molesof hydrogen are produced 2 moles of oxygen are produced. So we take 6.28 divide it by 2 and we wend up with 3.14.
