1. A system to simulate well bore hydraulic conditions for determining associated affects friction reducers have on fluids over a wide range of pressures and flow rate conditions for optimal results during fracturing comprising:
a primary feed tank adapted to store and dispense said fluids;
a mixing assembly connected below said primary tank and adapted to receive said fluids, and said friction reducers from a syringe pump for mixing with a propeller;
a variable pump connected to said mixing assembly and adapted to pass mixed said fluids and said friction reducers;
a computer;
a first loop adapted to pass mixed said fluids and said friction reducers from said pump to a first differential pressure sensor and adapted to determine a first pressure differential between said variable pump and said second differential pressure sensor;
a second loop adapted to pass mixed said fluids and said friction reducers from said pump to a second differential pressure sensor and adapted to determine a second pressure differential between said variable pump and said second differential pressure sensor;
a third loop adapted to pass mixed said fluids and said friction reducers from said variable pump to a third differential pressure sensor and adapted to determine a third pressure differential between said variable pump and said second differential pressure sensor;
wherein said variable pump, said first differential pressure sensor, second differential pressure sensor, and said third differential pressure sensor, and said a mixing assembly are in communication with said computer;
wherein said first differential pressure sensor, said second differential pressure sensor, and said third differential pressure sensor are connected to a conical secondary receiving tank having a spill over line to said primary feed tank; and
said system is adapted to provide adjustable shear rates that range from 500 to 6000 reciprocal seconds without said fluids recirculation back to said primary tank.
