V is the recommended peripheral velocity for the tool being used . D is the diameter of the tool . N. is the rotational velocity of the tool . Since the peripheral velocity is commonly expressed in units of f eet/minute and tool diameter is typically measured in units of inches, Equation 1 can be solved for the spindle or tool vel ocity,

What will happen is that the stream diameter will become smaller to account for the faster velocity. If the water were a bar of elastic material this would be the same as stretching it. It's mass flow is the same, it just elongates as it becomes faster. By the time it reaches the bottom of the vertical pipe the stream will not have a diameter of A.

Velocity Profiles In Verticle Mills On the Vertical Structure of Wind-Driven Sea Currents in ... The profiles of the relative (with respect to a 5-m depth) current velocity averaged over low and moderate wind speeds (from 4 to 8 m s −1 and from 8 to 12 m s −1, respectively) normalized by wind speed are plotted in Fig. 2a.
This Excel spreadsheet calculates and plots the velocity profile of a power-law fluid in a circular pipe. The spreadsheet is valid for Newtonian, pseudoplastic and dilatant fluids. The velocity profile of a Power-law fluid is given by this equation. where. r is the radial position i.e. distance from the center line (m)
Turbulent Velocity Profile: The Logarithmic Velocity Profile: The shape of the velocity profile within a turbulent boundary layer is well-established by theory and experiment. The profile has specific characteristics very close to the bed where viscosity controls the vertical transport of momentum, and different characteristics farther

A non-disturbing photochromic dye tracing flow visualisation technique has been applied to measure velocity profiles in two-phase flow in a 10 mm diameter pipe, using trichloroethylene and air as working fluids. Measurements are presented for vertical annular and slug flows.
The analysis at z / Dclass =−0.49 demonstrates that the velocity profile still correlates well with the expected relationship, however, the values for n and k are somewhat different. This difference is likely to be due to the influence of the different flow regime detected in the zone above z / Dclass =−0.49.

These applications are a simple way for coaches and researchers to measure an athlete's force-power-velocity characteristics during a vertical jump or sprint. This information can, therefore, inform coaches if an athlete is force- or velocity-deficient, as well as providing an optimal FV profile in which to work towards.
