4) a) Calculate the flow rate through the below smooth inlet pipe connected to a reservoir-with a 30-degree diffuser expanding to an 8 cm outlet. b) Calculate the flow rate

through the same pipe without a diffuser attached (so the exit diameter remains 5 cm) and explain the results. c) Calculate the flow rate through the same system with a sharp-edged expansion from a 5cm diameter pipe into an 8 cm diameter pipe. Is the flow rate higher or lower than in parts
