In a long pipeline with a sudden enlargement from 150mm to 300mm diameter, water flows at 2m/s and creates turbulence. Calculate the pressure loss due to this enlargement and discuss how to reduce it.
💡 Hint: Focus on diameter ratio and initial versus final velocities.
A pump elevates water from a reservoir to a storage tank 30m higher. If the pump is 85% efficient and the motor input is 10kW, calculate the flow rate to the tank based on the pump characteristics.
💡 Hint: Use the given height and efficiency to find usable power.
