[-tj_pname-]一台水泵50分钟内将60立方米的水抽到40米的高处.在这段时间内,水泵对水做的功是多少焦水泵输出功率是多少(g=10N/kg)_百度作业帮
一台水泵50分钟内将60立方米的水抽到40米的高处.在这段时间内,水泵对水做的功是多少焦水泵输出功率是多少(g=10N/kg)
水泵输出功率是多少(g=10N/kg)
60立方米水的重量是60吨,也就是60000kg；使水产生的位移是40m；取重力加速度g=10m/s^2水泵做功：6=（牛米）=24000千牛米1牛米=1焦耳.24000千牛米=24000千焦=24000kJ水泵对水所做的功是：24000kJ.如果要求功率的话,就要考虑时间了.水泵做功的时间是50分钟,也就是3000秒,2=8（kW）
