PIPES AND CISTERNS

PIPES AND CISTERNS

1.
t (A + B) = (tA * tB)/(tA + tB)

2.
tA = (tB * t (A + B))/(tB - t (A + B))

3.Time for filling , (Filling pipe is bigger in size.)

F = (e * f)/(e - f)

4.Time for emptying , (emptying pipe is bigger in size.)

E = (f * e)/(f - e)

5.
T(A + B + C)=L/[(L/tA) + (L/tB) + (L/tC)]

6.Pipes 'A' & 'B' can fill a tank in f1hrs & f2hrs respectively.Another pipe 'C' can empty the full tank in 'e'hrs.If the three pipes are opened simultaneously then the tank is filled in ,

F = L/[(L/f1) + (L/f2) - (L/e)]

7.Two taps 'A' & 'B' can fill a tank in 't1' & 't2' hrs respectively.Another pipe 'C' can empty the full tank in 'e'hrs.If the tank is full & all the three pipes are opened simultaneously . Then the tank will be emptied in,

E = L/[(L/e) - (L/f1) - (L/f2)]

8.A filling tap can fill a tank in 'f'hrs.But it takes 'e'hrs longer due to a leak at the bottom.The leak will empty the full tank in ,

E = [t(f * e) * tf]/[t(f + e) - tf]

9.Capacity of the tank is ,

F = (f * e)/(e - f)

10.
tc = [t(A + B) * t(A + B + C)]/[t(A + B) - t(A + B + C)]

11.
T = (xyz)/[(xz) + (yz) - (xy)]

sir,
we are happy to view your blog.
and one morething is we are not able to see shortcuts because they not visible correctly.so plz modify them.thankyou.

Could anyone tells - what does shortcut represent to what?
e-?
f-?
F-?
L-?
and so.....

F- Total time
f- filling time
e- emptying time
L- L.C.M
