Answer 2

Answer:

1:64

Explanation:

delta Pa=4T/R

Given,

delta Pa = 4×delta Pb

therefore, according to the problem

delta Pa÷delta Pb =4......(i)

4T/Ra ×Rb/4T

=Rb/Ra

So, putting this result in equation (i), we ge

Rb/Ra = 4

or, Ra/Rb=1/4

therefore, Va/Vb = (Ra/Rb)^3

or, Va/Vb= (1/4)^3

or, Va/Vb= 1/64
