Homework Help: Physics

Posted by mymi on Monday, November 7, 2011 at 3:42am.

Water at room temperature flows with a constant speed of 8 m/s through a nozzle with a square cross section, as shown in the figure. Water enters the nozzle at point A and exits the nozzle at point B. The lengths of the sides of the square cross section at A and B are 64 cm and 44 cm, respectively.

(a) What is the volume flow rate at the exit?

(b) What is the acceleration at the exit? The length of the nozzle is 2 m.

(c) If the volume flow rate through the nozzle is increased to 7 m3/s, what is the acceleration of the fluid at the exit?

I got the correct answer for a which is 3.27 m^3/s, help me on part b and c please.
