FUN Fan Study Unit Fluids Mechanics Lab Equipment Teaching Equipment


This unit consists of a centrifugal fan equipped with cylindrical suction and discharge ducts. The suction duct is provided with a static pressure tap connected with a differential pressure gauge, besides including a temperature sensor and an air damper (for varying the duct characteristic). The discharge pipe is provided with a static pressure tap connected with a differential pressure gauge, besides including a Pitot tube connected with a micromanometer, a temperature sensor and an air damper. Motor r.p.m. can vary continuously thanks to a digital inverter that also indicates the number of r.p.m. and the absorbed power.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Determining flow rate with Pitot tube
• Plotting the characteristic curve of a fan at different r.p.m. values
• Checking the laws of similarity (rpm vs m/s, rpm2 vs mmH2O, etc...)
• Determining the power absorbed by the motor versus r.p.m. and flow rate
