An oil of density 850 kg/m3 is pumped in a pipe of diameter 20 cm. The discharge is measured as 0.015 m/s. The
drop in pressure in a length of 800 m of pipeline, both ends of which are at the same elevation is measured as 98 kPa.
Assuming Re < 2000, calculate the value of absolute viscosity of the oil.
Ethanol with a density of 789 kg/m moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P, = 1.90 x 10“ Pa, and the pipe
diameter is 7.00 cm. At another point y = 0.35 m higher, the pressure is P, = 1.10 x 104 Pa and the pipe diameter is 3.50 cm.
