A liquid having coefficient of viscosity n flow through a tube of length at the rate of 100 cc per sec. The pressure difference between the entering and leaving end of tube is equivalent to p. A second tube of radius (r)/(2) but of same length is connected in series with first tube and is connected to the same source. Rate of pressure difference across 1 and 2 tube when they are connected in series is

1.	A liquid having coefficient of viscosity n flow through a tube of length at the rate of 100 cc per sec. The pressure difference between the entering and leaving end of tube is equivalent to p. A second tube of radius (r)/(2) but of same length is connected in series with first tube and is connected to the same source. Rate of pressure difference across 1 and 2 tube when they are connected in series is
