Example The velocity distribution for flow over a plate is gives by u = 2y - y² where u is the velocity in m/s at a distance y meters above the plate. Determine the velocity gradient and shear stress at the boundary and 1.5 m from it. Take dynamic viscosity of fluid as 0.9 N.s/m2.
Please solve following problem. Especially I cannot understand how to get flow rate.
If the hydraulic radius of a similar shell is 1.28 mm, the density of the fluid flowing in it is 974 kg/m3, the velocity of fluid is 37.1 m/s and the dynamic viscosity is 0.000641 P-s calculate the Reynolds number, Re of the fluid in the shell.
3.1 A cylindrical plug, 120mm long with a diameter of 95 mm, slides concentrically in a fixed cylinderwith an internal diameter of 95,2 mm. The radial clearance is filled with oil with a viscosity of 0.2 Pa.sCalculate the Force required to slide the plug along the cylinder at a speed of 5 m/s against the viscousresistance of the oil, the power lost due to the viscous resistance and the Kinematic viscosity of the oil ifits density is 850 kg/m 3 . A pressure intensifier is used in reverse deboost the pressure in a hydraulic system from 15MPa to7MPa. The volume of fluid required in the low pressure side is 700ml and the length of the stroke of thepiston is to be half the diameter of the low pressure piston. Calculate the diameters of the high-pressureand low pressure sides as well as the stroke length of the piston.
Need step by step solution
please help me with this exercise ...
I've been struggling about this problem. How can I get the fluid velocity from the Reynolds numbers. That is the required value for Re. If, the given values are Water Density = 10000 kg/m3, Diameter of tube = 0.05m and Dynamic Viscosity = 0.001 Pa-s. If the formula is Re = Vρd/μ.
Please help me question 2.6
plz plz help me with this one nowwwwww Two plates are separated by 30 mm space. The lower plate moves at velocity of 2 m/s while the upper plate moves at a velocity of 8 m/s. Oil (S=0.51) which fills the space. The oil viscosity is equal to 0.003 m2/s. The variation in velocity of the oil is linear. What is the shear stress in the oil (N/m2)?
