The figure below shows a branched system in which the pressure at A is 700 kPaand the pressure at B is 550 kPa. Each branch is 60 mlong.Neglect losses at the junctions but consider all elbowsin both branches. If the system carries oil with a specific weight of 8.80 kN/m3, calculate the total volume flow rate.The friction factor of the DN 100branch (call thisBranch a) is 0.02and the friction factor of the DN 80branch (call this Branch b) is 0.022. Assume all elbows are standard.(Answer: 6.07×10−2?3/?)

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
