• 延續上學期的進度將數據加以修正，並且將成品做出及測試，並以測試結果加以改善

• 用男性來計算，設年齡為20歲，身高為200 cm
• (27.63-0.112  20)  200  10-3 =5.078 公升
• (5078-1200)  2  10-3 = 7.756 公升
• 幫浦瓶半徑為3.5 cm儲氣半徑為15 cm ，兩者高度都為13 cm ，因此幫浦瓶體積約為500 cc，而儲氣瓶為8308 cc。

• 假設儲氣狀況為絕熱過程，k(比熱容比) = Cp/Cv = 1.4，其絕熱壓縮其壓力與容積變化爲
• 1.913 bar時所需外力約為355牛頓。
• 此時假若當壓力變為1bar，最後可放出氣體量為7.585 公升 。
