3. The discharge, Q (m'/s), over a notch depends on the head, H (m), the acceleration due to gravity, g (m/s), the density, p (kg/m), and the dynamic , (kg/ms). Using Buckhingham method, prove th...
H11.2 Water flows over a dam as illustrated in the figure. Assume the flowrate, q, per unit length along the dam depends on the head, H, width, b, acceleration of gravity, g, fluid density, r, and fluid viscosity, u. a) Why shouldn't you choose both H and b as repeating variables? b) Develop a suitable set of dimensionless parameters using the Buckingham Pi method and the FLT system for this problem using b, g, and p as repeating variables. Governing...
The drag force Fp on a smooth sphere falling in water depends on
the sphere speed V, the sphere density P. the density p and dynamic
viscosity of water, the sphere diameter Dand the gravitational
acceleration g. Using dimensional analysis with p. V and D as
repeating variables, determine suitable dimensionless groups to
obtain a reneral relationship between the drag force and the other
variables. If the same sphere were to fall through air, determine
the ratio of the drag...
For flow in a pipe of uniform diameter D the loss in hydraulic head, h, is given by: L u2 D 2 where L is the length of the pipe, u is the average flow velocity, g is the acceleration due to gravity and f is a constant. During reconfiguration of a plant it is estimated that the length of the pipe could be reduced by 15% and its diameter increased by 6%. Calculate the maximum percentage by which The...
Density p [kg/m2], viscosity - u [kg/ms], surface tension - o (N/m=kg/s2] compressibility K [Pa-kg/ms2] 1. For particles settling in a stationary fluid it is thought that the drag force FD of a small sphere is a function of the settling velocity of the sphere - V, the diameter of the sphere - d, and the density p, and viscosity of the fluid - . Determine the dimensionless relationship(s) between these variables (FD/HVd, pdV/H) 2. (a) The efficiency of a...
Question 3 [20 marks] Water (density p1000 kg/m2; dynamic viscosity 0.001 Pa-s) flows steadily through a horizontal, straight pipe with circular cross section of diameter D=0.2 m. The volumetric flow rate is 0.01 m°/s. Argue that this is turbulent flow. [4 marksl а. Pressure drop in the pipe is due to friction. The pressure drop per unit length can be written as Др 4f L with U the average velocity in the pipe and fthe friction factor. Given the pipe...
