About This Product
The football pump raises the pressure of the air in the bottle, and the U-tube manometer shows the pressure difference. Opening the large-bore stopcock lets the air expand quickly to atmospheric pressure, and the two manometer readings, h1 and h2, are used to work out the ratio Cp/Cv. Science Lab Export can supply the Clement and Desorme’s Apparatus to Saint Vincent and the Grenadines, Fiji, Tanzania, the United States and Sudan.
