A pump is required to deliver water at 20°C from a ground-level storage tank to an elevated reservoir located 25 m above the pump. The pipeline is 80 m long, made of commercial steel (absolute roughness = 0.045 mm), and has four standard 90° elbows and a gate valve (fully open). The desired flow rate is 0.02 m³/s. Determine: The total dynamic head (TDH) the pump must overcome. The pump power required if the pump efficiency is 70%. Suggest a pump type suitable for this application. Assumptions: Water properties at 20°C: Acceleration due to gravity: Minor loss coefficients: Each elbow: Gate valve:
