To help put the evaporation into perspective, I live on an 840 acre lake. Normal summer evaporation from the lake in summer is about 2300 GPM. That's average over 24 hours, peak evaporation during the day is much higher.

I agree with the post above, but get 70,000 GPM. 100 MW = 100E6 watts X 3.4 BTU/hr/W = 3.4E8 BTUH. 3.4E8 BTUH / 10 deg F X 1.0 lb deg F / BTU = 3.4E7 lbs/hr of water. 3.4E7 lbs/hr / 8.34 lbs/gallon / 60 min/hr = 70,000 GPM. If you get rid of the heat by evaporating water in a cooling...

We do not allow AI chatbots on the technical forums because their output cannot be trusted, and is frequently wrong. In your case, the AI is misleading you. Water flows downhill. If the water level in the Source A pipe is different from the water level in the Source B pipe, it will flow...

The inlet B with the riser will flow less than the inlet B with the T because of less restriction from elbows. If the supplementary inlet B is smaller than the inlet A, then it will make very little difference to the total flow. Some things you can do to improve flow: 1) Larger pipe. 2) Raise...

We have the same smoke in Northern Wisconsin. Visibility is less than one mile. I wore an N95 mask for my morning run, which helped.

I went for a run two days ago, of which 2.5 miles was a trail in the woods. Deer fly country. So I wore my deer fly hat with a new piece of fly paper. The hat worked well. I only whacked 5 or 6 of those miserable blood sucking varmints by hand. The deer fly population is slightly below...

The view from down by the lake yesterday while sitting in the shade of the tree on the left. Temperature 80 deg F (27 C). I saw 14 power boats at one time, with a family of loons (two adults, one young one) swimming in the middle. An otter swam by, dove under water, and came up chewing on...

Monarch butterfly caterpillar munching on a milkweed next to my driveway. Taken this morning with an Olympus TG-5 camera.

There is more to hopper design than that. Rather than walk through the design calculations, I suggest the two sites listed below. They do a better job of communicating hopper design than anything I would write. Good search terms to learn more are dry material hopper design. Those search...

I took this photo about two weeks ago. A pair of mallard ducks had been swimming around in front of my house. Then I started seeing only the female, and not very often. Ducks normally fly off with loud quacking when I got near, but the lone female would quietly move off a short distance. I...

Apple tree shot out a side window of my house four days ago. This tree has given 90 to 100 lbs of apples every year for several years now. I normally get about 40 lbs, the food shelf gets about 40 lbs, and deer get about 10 lbs of apples. Cell phone camera with minor cropping. Two cherry...

Thread reopened because of request by person who wants to make a post relevant to the original post.

This thread has fully answered the OP's original question, then circled around until all sight of the OP was lost. Thanks to all who contributed. Thread closed.

Thread reopened. I made a simple schematic sketch of what I think that mechanism is. Shaft 1 is geared to shaft 2. Shaft 3 is geared to shaft 4. Shaft 1 is connected to shaft 3 through a differential. Shaft 2 is connected to shaft 4 through a differential. Turning shaft 1 turns shaft 2...

BTDT, so I'm speaking from experience. You need a sufficient safety factor in the torque calculation. I suggest calculating torque based on 35 mm eccentricity between CG and center of rotation. With a safety factor that large, and your selection of bearings, you can ignore bearing friction...
