A compound pipe of diameter d1, d2 and d3 having lengths l1, l2 and l3 is to be replaced by an equivalent pipe of uniform diameter d and of the same length (l) as that of the compound pipe. The size of the equivalent pipe is given by
|
A.
\(\frac { l } { d^2 } = \frac { l_1 } { d_1^2 } + \frac { l_2 } { d_2^2} + \frac { l_3 } { d_3^2}\) |
|
B.
\(\frac { l } { d^3 } = \frac { l_1 } { d_1^3 } + \frac { l_2 } { d_2^3} + \frac { l_3 } { d_3^3}\) |
|
C.
\(\frac { l } { d^4 } = \frac { l_1 } { d_1^4} + \frac { l_2 } { d_2^4} + \frac { l_3 } { d_3^4}\) |
|
D.
\(\frac { l } { d^5 } = \frac { l_1 } { d_1^5 } + \frac { l_2 } { d_2^5} + \frac { l_3 } { d_3^5}\) |
