Flow over a cylinder can generate a Karman Vortex street under certain conditions. By using Buckingham Pi theorem for the dimensional parameters given below, find a relation for the vortex shedding in terms of the nondimensional numbers that you determine. Dimensional Parameters: Vortex shedding frequency f Freestream velocity, V Fluid density, P Fluid viscosity u Cylinder diameter, D

2. The wing on an aircraft is subjected to a drag F, created by airflow over its surface. It is anticipated that this force is a function of density p and viscosity u of the air, the length (characteristic) / of the wing, and the velocity V of the flow. Use FLT system to develop a set of dimensionless_parameters that can be used to investigate this problem. points) 120

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...

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

A small spherical ball of density p and radius a is released from rest and falls under gravity in a viscous liquid of density pf and viscosity u. Its vertical position is denoted by z(t), and we choose the origin such that z(0) = 0. The ball is subjected to two forces: its weight corrected for buoyancy F, = (p-p Vg, where g is the acceleration of gravity pointing in the - z direction and V = 47a/3 is the...
