a) A 30 cm diameter pipe, conveying water, branches into two pipes of diameters 20 cm and 15 cm respectively shown in figure 9. If the average velocity in the 30 cm diameter pipe is 2.5 m/s, find the discharge in this pipe. Also determine the velocity in 15 cm pipe if the average velocity in 20 cm diameter pipe is 2 m/s. V₁= 2.5 m/s D₁= 30 cm Question No: 9 (10 Marks) 6 m Figure: 9 (7 Marks) b) Differentiate compressible fluid and incompressible fluid with an example. (3 Marks) 3 a) Explain briefly about pitot tube and how it is used for velocity calculations (3 Marks) P₁= 39.24×10 N/m² D₁ = 0.2 m Datum Line b) An oil of specific gravity 0.9 is flowing through a pipe having diameters 20 cm and 10 cm at sections 1 and 2 respectively shown in figure 10. The rate of flow through pipe is 35 litres/s. The section 1 is 6 m above datum and section 2 is 4 m above datum. If the pressure at section 1 is 39.24 x10 N/m², find the intensity of pressure at section 2. 4m ↓ V₂= 2 m/s D₂= 20 cm 2 Figure: 10 V3=? D₂= 15 cm D₂= 0.1 m b) Explain the working of four stroke petrol engine with a diagram Page 8 of 9 (7 Marks) Question No: 10 (10 Marks) a) Using ideal gas equation, how much volume needed to store 0.050 moles of helium gas at 202.6 kPa and 400 K?
