1. Water flows at a rate of 25 L/s in a horizontal pipe whose diameter increases from 6 cm to 11 cm by an enlargement section. What is the mag the pressure change, in kPa? 2. The pipe flow in the figure shows a cylindrical surge tank. At t=0, the height of water inside the tank is 30 cm. How long will it take, in secon the remainder of the tank?

Question
ONLY ROUND OFF ON THE FINAL ANSWER. 1. Water flows at a rate of 25 L/s in a horizontal pipe whose diameter increases from 6 cm to 11 cm by an enlargement section. What is the magnitude of the pressure change, in kPa? 2. The pipe flow in the figure shows a cylindrical surge tank. At t = 0, the height of water inside the tank is 30 cm. How long will it take, in seconds, to fill the remainder of the tank? V₁=2.5 m/s D=75 cm d=12 cm 3. The ventilating fan of the bathroom of a building has a volume flow rate of 30 L/s and runs continuously. If the density of air inside is 1.20 kg/m³, determine the mass of air, in kg, vented out in one day. Bathroom 22°C Fan 30 L/s V₂=1.9 m/s Figure 4-4.
