About This Product
Air from the blower passes over the heating element, and the temperature indicator shows the difference in air temperature across it. Combining that rise with the airflow from the orifice meter and the heater input from the voltmeter and ammeter, students calculate the specific heat of air on this HEAT TRANSFER LAB apparatus.
Frequently Asked Questions
Q1. How is the specific heat of air found? Air is blown over the heating element; the temperature difference, the airflow from the orifice meter and the heater input from the voltmeter and ammeter give the specific heat of air.
