Thanks to all for the kind welcome & info, and especially to Ed Anderson for the spreadsheet. It will take a few days for me to work thru this info, but I’ll be back soon w/ more questions.

Jeff,

1.Multiply Hp x 42.4 to get BTU/Min.

Or 2545 BTU/ hr = 1 hp

2.Oil cooler cools 30 % of Rotary heat.

3.?

4. Up to 60 gal a min.

Welcome Jeff,

Have you searched the archives?

Subject: [FlyRotary] Renesis Cooling Thermodynamics

Hello All,

I’ve started the tail section of an RV-7A and want to power it w/ a Renesis. I need information about cooling thermodynamics.

Here are my questions:

How much heat must be rejected thru the coolant (in BTUs)?

How much heat must be rejected thru the oil?

What is the temp delta between radiator inlet/outlet in a typical installation?

What is the coolant flow (in GPM) for the stock Renesis cooling system?

If these questions have already been answered, please direct me to those answers.

Thanks for the help,

Jeff Luckey
