 Alright, so why did the stream of water from the hole near the bottom covered a greater horizontal distance? We know that water exerts pressure on the sides, right? That's why there are streams of water coming out. Now, if we look at the amount of water on the top of the two holes, we see that there is this much amount of water on top of the hole near the bottom and then there is this much on top of the hole above. So all the water inside the yellow circle will exert pressure on the hole below and all the water inside the blue circle will exert pressure on the hole above. Since the horizontal distance covered by the stream of water from the hole below is more, we can say that the water is exerting more pressure on the hole below and less pressure on the hole above. So finally, we can say that the pressure due to water or any liquid for that matter increases with height. You will experience more pressure if you are deeper inside a water body. That's why submarines which move deep inside the ocean have a really strong metallic hull so that it can withstand or bear the high pressure due to water on top of it.
