question 12

Multiple Choice

Motor oil, with a viscosity of $0.25 \mathrm {~N} \cdot \mathrm { s } / \mathrm { m } ^ { 2 }$ is flowing through a tube that has a radius of 5.0 mm and is 25 cm long. The drop in pressure is 300 kPa. What is the volume of oil flowing through the tube per second?

• A) \(4.7 \mathrm {~m} ^ { 3 } / \mathrm { s }\)
• B) \(0.0012 \mathrm {~m} ^ { 3 } / \mathrm { s }\)
• C) \(7.5 \mathrm {~m} ^ { 3 } / \mathrm { s }\)
• D) \(0.025 \mathrm {~m} ^ { 3 } / \mathrm { s }\)
• E) \(0.00038 \mathrm {~m} ^ { 3 } / \mathrm { s }\)
