Water flows through a valve with inlet and outlet velocities of 3 m/s. If the loss coefficient of the valve is 2.0, and the specific weight of water is 9800 N/m3, the pressure drop across the valve is most nearly:

9,000 kg/ms^2

Explanation:

The computation of the pressure fall across the valve is shown below:

It is to be computed by using the following formula

where,

= Fall in pressure

k = Coefficent loss

P = Loss of density

V = velocity of water

But before reach to the final solution first we have to determine the loss of density which is

Now put all other values to the given formula

So,

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
