Chemical Engineering > GATE 2011 > Flow in Pipes
Two liquids (P and Q) having same viscosity are flowing through a double pipe heat exchanger as shown in the schematic below.
Densities of P and Q are 1000 and 800 kg/m3 respectively. The average velocities of the liquids P and Q are 1 and 2.5 m/s respectively. The inner diameters of the pipes are 0.31 and 0.1 m. Both pipes are 5 mm thick. The ratio of the Reynolds numbers ReP to ReQ is
