Question 43
XE-BNAT2 marksNeeds review
An oil of density 870 kg/m
and viscosity 0.036 Pa.s flows through a straight pipe of 10 cm diameter and 1.5 km length at the flow rate of 250 liters per minute under the steady and incompressible flow conditions. To control the flow rate of oil, a valve is fixed at the middle of the pipe causing no change in the total length of the pipe. The total head loss measured across the two ends of the pipe is 11.60 m. Using gravitational acceleration as 10 m/s
, the minor head loss contributed by the presence of the valve in m (rounded off to 2 decimal places) is ________Log in to check the answer
