Solve each problem involving the basic properties of thermodynamics and fluid mechanics. Write your complete solution on a separate sheet paper. Use two decimal places for your final answers.

Note: Use the table of standard atmospheric pressure for the conversion of the pressure units

Problem 3: Bernoulli's Principle relates the pressure ,velocity and elevation of a fluid flow. It can be mathematically expressed in terms of head as : 2 VB 2 PA VA PB + + ZA - hloss = + + ZB 29 Y 2g PA PB where: and = pressure head at point A and B V 2 2 VA VB and = velocity head at point A and B 2g 2g ZA and zy = elevation head at point A and B hloss = head loss An oil having a specific gravity of 0.84 with a volume flow rate of 56 L/s is flowing in a pipe as shown in figure 2. The total head loss from point A to point B is 900 mm. Calculate the gage reading or Pressure at point B in kPa.Gage reading = 445 kPa A Oil in diameter = 150 mm WW OST = JajawDip Gage reading = ?kPa ZA =13.21 m B Oil out diameter = 225 mm Za #1.2 m datum line Figure 2.
