Question # 5
a. Briefly explain how the Bernoulli equation is derived. Discussits application in oil / gas productions, including its limitation.[4 marks]
b. The water level in a tank shown in Figure Q5b is 20 m above theground. A hose is connected to the bottom of the tank, and thenozzle at the end of the hose is pointed straight up. The tankcover is airtight, and the air pressure above the water surface is4 atm gage. Assuming the system is at sea level, determine: [5marks]
i. The maximum height to which the water stream could rise.
ii, If the water level in the tank was 15 m, would the maximumwater rise at the nozzle increase? Justify with calculation. (4marks]
iii. If the gauge pressure increases to 5 atm for 20 m water level,show the formula of finding water velocity at the nozzleexit. [4 marks] 4 atm 20 m Figure Q5b
