Would anything go wrong or be undesirable about using big 1.5/2/whatever" layflat hose with adapter fittings on a transfer pump designed for 3/4 GHT?

Looking to pump water ~300ft laterally but with a vertical rise of only about 10", thinking big layflat discharge hose would be good to reduce friction loss, and it packs smaller than garden hose. But I've never seen anyone do it, would it drop the pressure or something? Kink too easy because the hose is empty? Are these terminally stupid questions? I know the suction hose has to be equal or larger diameter.

Yeah it can cause priming and velocity problems. Just use a garden hose

You can put anything larger on the outlet side, it doesn't matter. On the inlet side, it has to be a solid structure pipe (ie. garden hose), obviously a roll-up pipe cannot be used for suction. For diameter, you'd likely have to manually precharge the whole hose and the pump to start pumping, if it's a very large pipe on a smaller pump that is supposed to be self-priming.

What kind of velocity problems?

>>2945764
But it should work normally if manually primed?
>>
>>2945766
Yeah, a larger pipe just means less resistance, the pump doesn't give a shit as long as you meet its ratings. It's definitely not gonna be able to suck from deeper or push higher up at all, but you'll get better throughput from lower pipe resistance.
If you massively increased the outlet pipe diameter while keeping the original inlet pipe diameter, you could also potentially get cavitation that is long-term damaging to the pump's body, so try to not do that. Cavitation is noisy so you'd probably notice it's happening if it was happening.

Would a matched 1.5/2/whatever suction hose eliminate that possibility? Or could it arise from within the little intake pipe on the pump itself?
>>
>>2945781
I would use the intended garden hose intake. A battery powered pump like that probably won’t benefit worth a damn.

Anybody know physics well? Anon’s “velocity issues” are bullshit, but a 2” hose full of water going up 10ft weighs a ton more than a 3/4” hose full of water. Does feet of head pressure or whatever account for the diameter of the hose/ volume or water you’re trying to push uphill? I would google that, like does blowing water up a 10’ verticle drinking straw require more work than blowing water through a 2” piece of PVC?
>>
>>2945781
I'd just stick on whatever pipe I want and worry about problems later, if they occur.
>>2945797
The weight of the column doesn't change anything, only the height.
>>
People use lay flat hoses to discharge water from backwashing pool filters without issue. It wouldn't work on the intake as others have suggested but I see no reason it wouldn't work for the outflow. It will hold a lot of water when done due to the rise but you can solve that by just lifting up the pump end.

>The weight of the column doesn't change anything, only the height.
Because the higher the water column is, the greater the weight of water in it. More water = more weight. More weight = greater head pressure.
>>
>>2945932
The retarded tripfag was asking if, when you have more water in one body, as in a thicker hose, its total weight would have an effect on the pump. So the answer is, no, it doesn't matter if you have a 1mm diameter pipe that's 10m high or a 1km diameter pipe that's 10m high, both of them have the same pressure at the bottom, and the pump faces the same head pressure. The relation of the water column's height to pressure isn't related to total weight, only specific weight and height. P = h * ρ
>>
>>2945939
That was the question. Too lazy to google the equation.

Is there more pressure at a 3/4” outlet on the bottom of a 10ft tall tank full of 20k gallons of water? Or a 3/4” garden hose 10’ long standing vertically full of water?

If physics says they’re the same, well I guess they’re the same. Gravity does what it does.
>>
>>2946095
Somehow you don't sound like you're asking the question honestly. Like you're saying well obviously pfft it's the 20k gallon tank.
