Hi, in this question a water is flowing through the diverging frictionless pipe as shown at a flow rate of q dot with the given parameter.
00:12
So the value of q dot is given as 500 meter cube per hour.
00:19
We have pressure at point one as 500 kilo pascal.
00:24
We have the value of z1 as equals to 3 meter.
00:29
We have z2 as equals to 14 meter.
00:33
The value of diameter d1 is 400 mm and d2 is given as 500 mm.
00:43
Also the sg value of water is 1.
00:46
So first of all in part a we have to calculate the inlet velocity.
00:54
So here we have from this figure this is point one, this is point two, this distance is z1, this is z2 and this angle over here is given as theta.
01:10
So now first of all the value of rho that is density of water will be 1000 kg per meter cube.
01:22
Now from continuity equation we can write a1 v1 as equals to a2 v2 and this will be equals to q.
01:35
So now we can write 500 divided by 3600 as equals to pi by 4 d1 square v1 or this will be equals to pi by 4 d2 square v2...
