An important dimensionless parameter in certain types of fluid flow problems is the froude number defined as v/√g. l where v is a velocity, the acceleration of gravity g, and a length l. determine the value of the froude number for v=10ft/s, g=32.2ft/s2, l=2 ft and recalculate the froude number using si units for and explain the significance of the results of these calculations.

1.24611

Explanation:

V = Velocity = 10 ft/s

L = Length = 2 ft

g = Acceleration due to gravity = 32.2 ft/s²

Froude number is given by

Converting to SI units

The Froude number is 1.24611

The Froude number is equal. The Froude number is dimensionless as the units cancel each other. In order for this to happen the units used need to be consitent either imperial or SI.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
