Abstract
A closed-loop flow circuit, incorporating a canned pump, has been developed for calorimetric studies on compressed water at pressures up to 100 MPa (MN/m2). The pump, which has a peripheral impeller, develops a maximum differential pressure of over 0.30 MPa and produces mass flow rates of up to 0.25 kg/s. The pump and associated flow circuits exhibit especially good flow stability. A unique pressurizing system is employed to raise and adjust the pressure in the pump and circuit. The oil and water pressures are equalized in a vessel where the oil/water interface is monitored using a capacitance method. Pump characteristics and associated calibrations are reported.
