Hello students, in this question, pair model and prototype is given.
00:12
Details of pair model is given.
00:15
Now we need to find speed, force, height and coefficient for prototype.
00:22
First we need to find speed.
00:25
For that we can use frode law which states that v by root gl of model is equal to v by root gl of prototype.
00:43
From this we need to find prototype value.
00:47
For that rearranging the formula velocity of prototype is equal to velocity of model into root of gl value of prototype divided by gl value of model.
01:04
Here this ratio is given 1 by 20.
01:07
Here taking prototype by model therefore that ratio become 20 by 1 and flow rate is given 0 .6.
01:15
Substituting for that we get velocity of prototype as 2 .6833 meter per second.
01:30
Next we need to find force.
01:32
Force is proportional to scale ratio power whole cube.
01:41
Scale ratio is that is 1 by 20 and again considering force of model by force of prototype.
01:52
We need to find force of prototype.
01:56
For that here force of prototype sent to this side 20 cube will send to numerator...
