The development of a double leg elbow proportional fluid amplifier to handle 5.85 gpm 

 of water flow rate is described in detail. The amplifier has linear output flow characteristics with 

 a gain of 50 and can switch flow from one output to the other completely. Based upon the 

 experimental results, analytical expressions are developed which clearly show the effects of the 

 active and passive legs flow parameters, the control flow, and the size and location of the output 

 ports on amplifier's performance and they can be used in designing an amplifier of a desired flow 

 capacity. Analytical expressions to predict the performance of the amplifier are also given. A 

 mixing element comprised of two double leg elbow amplifiers stacked together to mix two fluids 

 was designed and tested successfully.
