Some are run with 3/8 hydraulic hose and some with 1/2"

 

What is the max flow rate of a 3/8 and 1/2 hose?

 

Presumably a small 3/8 hose will have a lesser flow rate per minute and slower to operate or am I missing the point?

 

I haven't got figures to hand but anything over 50litres/minute will need bigger bore than 3/8". Also you may operate the loader at fast tickover but unless you switch the pump off whenever you run the engine at higher speed the oil is thrashing around fasted in the feed and return to the valve block.

 

Thinner hose withstands higher pressure, but 1/2" is likely good enough in forestry/ agricultural uses. Main point is too narrow a bore for the flow rates heats up the oil and puts more stress on the pump.

Pressure loss for a given flow rate is directly proportional to length so longer pipes will need a bigger bore. Pressure loss through a pipe, fitting or valve costs power which will be converted into heat.
