A downhole apparatus for use in a wellbore includes a housing having at least one passage or cavity capable of receiving a fluid. The downhole apparatus further includes an orifice in fluid communication with the passage or cavity. A viscosity-altering member is positioned in proximity to the orifice and is capable of being activated to change the viscosity of the fluid and thus a rate at which the fluid is able to pass through the orifice.
