The rate of flow of water through a horizontal pipe is 200+last two digits of your id lit/s. The area of the pipe suddenly enlarges from 300 cm2 to 1200 cm2 . The pressure intensity in the smaller pipe is 10+last digit of your id N/cm2 . Determine: a) Loss of head due to sudden enlargement b) Pressure intensity in the larger pipe c) Power lost due to enlargement    Explain with clear writing and units and diagram  Also if you use tables and equation mention it with explanation

Answer the following:  a.) Friction factorb.) Determine the pressure drop per meter of pipe

A 140 m long pipeline runs between two reservoirs, both ends being under water, and the intake end is square-edged and non-projecting. The difference between the water levels in the two reservoirs is 40m. a) What is the discharge if the pipe diameter is 20 cm and f = 0.007? The density of water may be taken as 1000 kg/m³. b) When this same pipe is old, assume that corrosion reduces the diameter to 18 cm and that f becomes 0.012. What will the rate of discharge be then?

Water flows through a 15-cm diameter (D) pipe with a velocity (V) of 8.5 m/s as shown below. The relative roughness of the pipe is 0.004, and the loss coefficient for the exit is 1.04. Given that the kinematic viscosity is 1.12 x 10-6 N/m².s. Open 1 2 2.5 m D )cm v ) m/s 2.5 m- Determine the Reynolds number, Re. Determine the friction factor. Compute the total head losses (major and minor).

Scenario 2:Water flows through a 2cm diameter pipe at 1.6m/s with kinematic viscosity of 1.31 × 10-6 m2/s and densityof 1000 kg/m3. Using the Buckingham Pi Theorem:f) Calculate the Reynolds number.g) Find the velocity required to give the same Reynolds number when the same pipe is transportingair.h) Obtain the ratio of pressure drops in the same length of pipe for both cases.i) Reflect on the case studies provided—Food Processing Industry, Chemical Manufacturing, and WaterTreatment Facilities. Evaluate how the dimensional analysis using the Buckingham PiTheorem applies to these scenarios and discuss the specific challenges encountered, suchas variable fluid properties and complex fluid dynamics which are not always captured by thetheorem. Offer practical recommendations for engineers to tailor dimensional analysistechniques to the unique requirements of each case study scenario, optimizing design andoperational efficiency.For air, the kinematic viscosity is 15.1 × 10-6 m2/s and the…

Question A2 Figure QA2 is a schematic view of a river flow down an infinite hill with a constant angle of 0. Assume the viscosity and density of water are μ and prespectively. Furthermore assume in this motion the depth of the river remains unchanged and pressure is constant. a) List all the assumptions that you make in order to simplify the conservation of mass and N-S equations. b) Derive and list the simplified equations. c) Find a general solution to the velocity distribution across the river depth and then by applying the appropriate boundary conditions find an expression for the velocity profile. d) Determine the depth of the river in terms of volume flow rate Q per unit width.
