一、液体压强和深度的关系1.取一塑料瓶(大小似娃哈哈矿泉水瓶即可)在瓶壁用刀片有规则地划一些刻痕,装满水,然后用中间插有细玻璃管的胶塞塞紧.2.再取一装适量水的大烧杯,用1.5米—2.0米的乳胶管一端插在水中,另一端接抽气筒进行抽气,当水从管口流出后,再把乳胶管套在瓶塞的玻璃管上3.逐渐提起烧杯的竖直高度,就会有水从瓶壁的刻痕喷出,举得越高,水喷得就越急,如
First, the liquid pressure and depth of the relationship 1. Take a plastic bottle (size like Wahaha mineral water bottle can be) in the wall with a blade regularly ruled some nicks, filled with water, and then with a thin glass tube in the middle of the glue Plug tightly. 2. Take a large beaker of water. Insert one end of the latex tube 1.5 meters to 2.0 meters into the water. Connect the other end to the pump to extract air. After the water flows out of the nozzle, take the latex. The tube is sleeved on the stoppered glass tube. 3. Gradually lifting the vertical height of the beaker, water will be ejected from the nick of the bottle wall. The higher the lift, the more turbulent the water will be sprayed.
