Design of Experiment for Lab 5...

Description

Design of Experiment Objectives: To understand how various heat exchangers function To understand how inlet temperature and flowrate variations can affect heat exchanger performance

Variables: Independent: Flow rate of hot water, Temperature of hot water Dependent: Temperature Readings

Procedure: Variation of Hot Water Inlet Temperature: 1) 2) 3) 4)

Fix the hot water and cold water flow rates Set the hot water inlet temperature to 60 degrees Celsius Record all applicable temperatures using the thermocouples Repeat for starting temperatures of 40 and 50 degrees Celsius

Variation of Hot Water Flow Rate: 1) 2) 3) 4)

Fix the hot water temperature and cold water flow rate Set the hot water flowrate to 1 ks/s Record all applicable temperatures using the thermocouples Repeat for hot water flow rates of 2 and 3 kg/s...
