Question 4 A non-viscous fluid flows in a horizontally-placed pipe. When it goes through a wider section, what happens to the flow speed of the fluid? The flow speed increases The flow speed decreases. The flow speed does not change. O It cannot be determined. Question 5 1 pts It cannot be determined in which pipe the fluid has larger pressure difference. The pressure difference of the fluid is the same in Pipe 1 and Pipe 2. The fluid in Pipe 2 has larger pressure difference. The fluid in Pipe 1 has larger pressure difference. A viscous fluid flows in two different pipes. Pipe 1 has a length L₁, and Pipe 2 has a length L If both pipes have the same diameter and L₁ is shorter than L₂, choose the correct statement about the pressure difference of the fluid in Pipe 1 and Pipe 2. Question 6 1 pts 1 pts Calculate the pressure in the unit of kPa when 58 N of force is applied to 70 cm² of area. Be careful with units.
