为了提高给水压力,解决住宅楼区的供水问题,我院设计安装了一套无充气设备的气压给水装置。根据波义耳定律的基本理论推导出气压罐总容积和死水容积的计算公式如下:V=(γV_s)/(1-α)(1)V=(V_s(γ-1))/(1-α)(2)式中V——气压罐的总容积(米~3);V＇——气压罐死水容积(米~3);V_s—罐中调节水容积(米~3);α——罐中最小与最大工作绝对压力 In order to increase the pressure of water supply and solve the problem of water supply in residential buildings, our institute has designed and installed a pneumatic water supply device without inflatable equipment. According to the basic theory of Boyle’s law, the formula for calculating the total volume and dead volume of the air pressure tank is as follows: V=(γV_s)/(1-α)(1)V=(V_s(γ-1))/(1- α) (2) where V - the total volume of the pressure tank (meter ~ 3); V’ - dead volume of the pressure tank (meter ~ 3); V_s - regulate the volume of water in the tank (meter ~ 3); α - - Minimum and maximum working absolute pressure in the tank
