Fluid mechanics:

Please help me with this 2 question i really need it but if you only can solve one of it. Please do the Question 1. Dont skip any calculation please.Thankyou

Question 1 (12 Marks) Figure 1 shows water flowing through a venturi meter with diameter reduces from 8 cm to 4 cm at the throat. The pressure difference measured using a mercury (SG=13.6) manometer is 1.0 m. Determine the volumetric and mass flow rate assuming no losses. Throat 0 V. P Flow V P2 Manometer Figure 1. Venturi meter Question 3 (15 Marks) (a) A 60 cm diameter pipe is used to transfer water flowing at 7.5 m/s, from a large tank to a turbine, which exits to a lake located 20 m below the tank water surface. The turbine- generator has a combined efficiency of 75%. Determine the electric power output. Disregard any losses. (11 marks) (b) What are the possible losses that can occur in part (a)? Is the electric power output expected to be higher or lower if these losses are to be considered? Explain. (4 marks)
