摘要
本文利用功能原理及理想气体绝热方程,推导获得水火箭发射初始速度、喷水时间以及射程的表达式.利用上述表达式对水火箭发射的初始速度、喷水时间及射程进行了理论计算,并对水火箭内盛装水的体积和发射角度的最佳值进行了理论计算与研究.
According to the principle of work and energy and ideal gas adiabatic equation,the expressions of the initial velocity,the time of jetting water,and the launch distance of water rocket are deduced.Based on the expressions,the initial velocity,the time of jetting water,and the launch distance of water rocket are calculated theoretically.Optimum volume of water in the water rocket and the best launch angle are also investigated.
