question 68

Multiple Choice

Water, which we can treat as ideal and incompressible, flows at 12 m/s in a horizontal pipe with a pressure of $3.0 \times 10 ^ { 4 } \mathrm {~Pa}$
If the pipe widens to twice its original radius, what is the pressure in the wider section?

• A) \(9.8 \times 10 ^ { 4 } \mathrm {~Pa}\)
• B) \(4.9 \times 10 ^ { 4 } \mathrm {~Pa}\)
• C) \(7.4 \times 10 ^ { 4 } \mathrm {~Pa}\)
• D) \(3.0 \times 10 ^ { 4 } \mathrm {~Pa}\)
