What is the pressure difference between the two ends of a horizontal tube filled with glycerine, which has a length of 1.5 m, a radius of 1.0 cm, and has glycerine flowing through it at a rate of 4.0 × 10–3 kg

{{s}^{-1}}

per second? (Given: Density of glycerine = 1.3 × 103 kg

{{m}^{-3}}

and viscosity of glycerine = 0.83 Pa s).

Options

A6.4 × ${{10}^{2}}$ $Pa$
B9.8 × ${{10}^{2}}$ $Pa$
C11.4 × ${{10}^{2}}$ $Pa$
D1.55 × ${{10}^{2}}$ $Pa$

Correct answer

B. 9.8 × ${{10}^{2}}$ $Pa$

Step-by-step solution

Correct Option is : (B)
9.8 ×

{{10}^{2}}
