Hello, as in this question, h is equals to 20 sb is equals to 11 ,772 w here, kw, kilowatt, and d not is equals to 3 .5m here, db is equals to 1 .75m here, alpha is equal to 35 degree as here, and toe knot is equals to here, as here, to h is equals to 88 % percent.
00:35
And tone o is equal to 84 % here.
00:39
So as we know that 2 not is equals to sp divided by hp here, wp here.
00:46
So by simplifying this as here wp is equals to pgqh divided by 1000 here.
00:57
So as 0 .84, wp equals to 0 .84 11 ,772 divided by pgqh divided by 1000 here.
01:05
By simplifying this, q can be written as here 11 ,772 into 10 ,000 divided by 1 ,000 divided by 0 .84 into 1 ,000 into 9 .8 into 20 here by simplifying this, this one equals to 71 .4 to 8 meter per second here.
01:26
So q can be written as here, q is equals to pi by 4 into d, do square minus of d b square into v of f1 here.
01:34
By substituting value here 71 .428 is equal to pi by 4 into 3 .5 square minus of 1 .75 square into v.
01:44
F1 here.
01:45
So, v of f1 can be written as here 7 .71 .2 .4 .28 divided by complete term...
