A Fluid Is Flowing with an Average Speed of $0.0034 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$

Multiple Choice

A fluid is flowing with an average speed of 1.5 m/s through a tube that has a radius of 2.0 mm and is 18 cm long. The drop in pressure is 967 Pa. What is the viscosity of the fluid?

A) $0.0034 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$
B) $0.0018 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$
C) $0.028 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$
D) $0.0056 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$
E) $0.013 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$
