Unformatted text preview: Physics 2C, Waves ...Optics-- Winter 2007 Instructor: B. Grinstein Quiz # 4 INSTRUCTIONS: Fill, tear and return the bottom strip of the front page with your scantron. Keep the top portion of the front page and the rest of the quiz. Use a pencil #2 to ¡ll your scantron. Write your code number and bubble it in under “EXAM NUMBER”. Bubble in the quiz form (see letter A-- D at bottom of page) in your scantron under “TEST FORM” 1) A valve is closed and the ¢uid within a pipe is stationary. When the valve is opened, ¢uid ¢ows through the pipe. What happens to the pressure in the pipe when the valve is opened? A) The direction of the pressure change depends on the density of the ¢uid. B) The pressure decreases. C) The pressure remains the same. D) The direction of the pressure change depends on the direction of the ¢uid ¢ow. E) The pressure increases. 2) A pressurized cylindrical tank, 5.0 m in diameter, contains water which emerges from the pipe at point C, with a velocity of 29 m/s. Point A is 10 m above point B and point C is 3 m above point B. The area of the pipe at point B is 0.05 m 2 and the pipe narrows...
