Question

SAE 30 oil ows between parallel plates 8 mm apart, a shows in the fire below. A mercury manometer, with wall preure tape 1 m apart, egisters a 6 cm height, as shown The velocity profile for plane Poiseuille Bow in given by y)- K1-4)whenseming the reference coordinate axes on the bottom plate SAE 10 oil 6 cm Mercury Calculate the oil's pressure drop per unit length between the pressure taps, in Pa/m Chat is the velacity profile, u(y), for the flow of oil? (simplify the equation to the greatest extent possible) m/s)

Answer 1

In the Given problem Let us suppose the four point A, B, C and D in the Given figure. Also suppose the density of SAE 30 OIL will be 875.4 kg/m2 and mercury will be 13000kg/m2.

Po Po = (13000 -845-4) *9.818 G 100 = 12124.6x9.81*6 PAP= 4136.53 Pa ( 12 ) dAB = length b/w A 4B = im' PA PB = Prennure drop per unit length JAR I - 7136.53 7136.53 Pa (i) The Image of quention will be blure so it is unable to solve the and part of the problem
