Answer and explain why?

2. Although there are many types of fittings, we can calculate the pressure drop caused by each one using
a. pump efficiency curves.
b. equivalent lengths.
c. sphericity factors.
d. a metric socket set.
3. The Ergun equation is valid for
a. laminar flow.
b. turbulent flow.
c. both laminar and turbulent flow.
d. neither laminar nor turbulent flow.

Solution

solution for question2-

pump efficiency curve used to select the proper pump for a particular application

A socket set is a type of wrench that has a socket attached at one end, usually used to turn a fastener.

Sphericity is a measure of how spherical (round) an object is

Equivalent lengths is used to calculate the pressure drop.

The equivalent length method (L/D ratio) allows the user to describe the pressure drop through a fitting as a length of pipe. In theory the pressure drop through the fitting is equivalent to the pressure lost through a certain length of piping at that corresponding flow rate.

ypically as the fittings size increase the flow coefficient (L/D ratio) decreases, thus at pipe sizes larger than those at which the fittings equivalent length was determined the pressure drop will be over-estimated. At smaller pipe sizes than those at which the equivalent length was estimated the pressure drop will be under-estimated.

The advantage of the equivalent length method is that it is very simple to calculate. All pipe runs and fittings can be summed up to make one total length, and the pressure loss calculated from this length.

option (b) is correct
