1. Electric Waterpumps (score: 1): Author: Unknown; Date: Wed, 17 Mar 1999 11:17:03 -0500; All this talk about electric water pumps raises a few questions: 1) If the pump and drive pulleys are sized for adequate coolant flow at idle will the pump caviate at red-line? 2) How much power does; /html/triumphs/1999-03/msg01064.html (8,186 bytes)
2. Re: Electric Waterpumps (score: 1): Author: Unknown; Date: Wed, 17 Mar 1999 22:52:47 GMT; Over the RPM range. And in particular (see below): How does it respond to a partly closed thermostat? I've never seen an answer to that. Or rather: What is required in terms of coolant flow to proper; /html/triumphs/1999-03/msg01118.html (8,366 bytes)
3. Re: Electric Waterpumps (score: 1): Author: Unknown; Date: Wed, 17 Mar 1999 18:12:28 -0600charset="iso-8859-1"; Seems to me that my 1989 Audi 200 Turbo (God, I loved that car...) had an electrically driven water pump for the purpose of maintaining flow through the block after shutdown. As for power consumed, t; /html/triumphs/1999-03/msg01121.html (11,067 bytes)
4. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Wed, 17 Mar 1999 16:51:12 -0800; Nice analysis ! One quibble : your illustration is for minimum flow to keep the engine cool at full output. Now, we need the flow required at idle to size the pump (which I suspect is worst case, but; /html/triumphs/1999-03/msg01130.html (13,045 bytes)
5. Re: Electric Waterpumps (score: 1): Author: Unknown; Date: Wed, 17 Mar 1999 20:34:55 -0600charset="iso-8859-1"; For centrifugal pumps, flow is directly proportional to speed and power increases as the cube of the speed. Thus, if a pump runs at twice its normal speed it consumes eight times the power. At idle,; /html/triumphs/1999-03/msg01141.html (14,275 bytes)
6. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Thu, 18 Mar 1999 10:49:59 -0800; So, another way to look at this is : 12 lb/hr fuel. If 1/3 of the input heats the water, then using your equation, with a 2 ft head and 20 deg rise gives us .0067 hp for the pump. Then, using the cub; /html/triumphs/1999-03/msg01192.html (16,180 bytes)
7. Re: Electric Waterpumps (score: 1): Author: Unknown; Date: Thu, 18 Mar 1999 15:42:48 -0600charset="iso-8859-1"; Actually, the fuel flow rate was .5 PINTS/BHP/Hr, not lbs/BHP/Hr. Thus, under the conditions you have stated and using my initial assumptions, the heat equivalent of 24 BHP would be about 61,100 BTUH; /html/triumphs/1999-03/msg01206.html (10,254 bytes)
8. Re: Electric Waterpumps (score: 1): Author: Unknown; Date: Thu, 18 Mar 1999 17:21:55 -0500; Wow! Someone with the figures. I used to know about half of that stuff haven't used it in years. BTW I think the reason to keep the pump running after shut down is to cool the turbo bearing (Is it wa; /html/triumphs/1999-03/msg01208.html (7,891 bytes)
9. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Thu, 18 Mar 1999 16:05:09 -0800; Well, the rough approximation of a pint's a pound (the world 'round) seemed good enough for the precision required, and I DID assume a reduced head of 2 ft at 1250 rpm. This has to be about the minim; /html/triumphs/1999-03/msg01220.html (10,095 bytes)
10. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Thu, 18 Mar 1999 18:54:12 -0800; Forgot it's a closed system ! The height of the radiator has nothing to do with the head at the pump. Guess I'm getting too senile to think about new things <g> Randall seemed good enough for the pr; /html/triumphs/1999-03/msg01224.html (10,611 bytes)
11. Re: Electric Waterpumps (score: 1): Author: Unknown; Date: Thu, 18 Mar 1999 22:49:38 -0600charset="iso-8859-1"; Yes, that's correct. The head seen by the pump is a combination of static head (the difference in height between the level of fluid on the suction side and the level of the fluid on the delivery side; /html/triumphs/1999-03/msg01244.html (12,180 bytes)
12. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Fri, 19 Mar 1999 09:05:06 -0500; over 1 hp at 7000 rpm thats too bloody much.; /html/triumphs/1999-03/msg01259.html (7,286 bytes)
13. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Fri, 19 Mar 1999 14:50:33 +0000 (GMT); Considering that the 4cyl TR engine At least the TR will get a decent flow of air over it's radiator and not have to drag a monster plough, trailer, etc up a muddy one in four!

15. RE: Electric Waterpumps (score: 1): Author: Unknown; Date: Fri, 19 Mar 1999 12:05:24 -0800; See if you agree with this reasoning : There are two major flow resistances, the radiator, and the block/head. The radiator is between the radiator cap and the pump inlet, the block/head is between; /html/triumphs/1999-03/msg01286.html (9,381 bytes)
