A V-element meter is used to measure the flow of a 15 percent slurry of ion-exchange beads

Question:

A V-element meter is used to measure the flow of a 15 percent slurry of ion-exchange beads in water. The slurry is carried in a 3-in. Schedule 40 pipe, and the expected range of flows is 30 to 150 gal/min. The particle density is 1,250 kg/m3, and the average particle size is 250 μm. 

(a) What is the expected pressure drop at maximum flow if the V element or wedge extends across two-thirds of the pipe diameter? 

(b) If the differential pressure transmitter has an accuracy of 0.05 lbƒ/in.2, what is the accuracy of the flow measurement at maximum and minimum flows?
