Hi Guys,
I've recorded engine data and two of the variables recorded were engine speed and coolant temperature. To determine friction torque, the table below needs to be used:

The values in the main body of the table are friction torque. I would like to be able to calculate friction torque for a range of engine speeds and coolant temperatures. I think I have to interpolate the table to do this. How do I interpolate the table on Excel?
Below is a small sample of my spreadsheet. I would like a formula to calculate the friction torque by using the values in the engine speed and coolant temperature columns, and then using the table above. Any suggestions?

I've recorded engine data and two of the variables recorded were engine speed and coolant temperature. To determine friction torque, the table below needs to be used:

The values in the main body of the table are friction torque. I would like to be able to calculate friction torque for a range of engine speeds and coolant temperatures. I think I have to interpolate the table to do this. How do I interpolate the table on Excel?
Below is a small sample of my spreadsheet. I would like a formula to calculate the friction torque by using the values in the engine speed and coolant temperature columns, and then using the table above. Any suggestions?
