Materials: The mud density is determined using the mud balance shown in Fig. 1. This 4-scale instrument provides an accurate way to measure some parameters which are: Fig. 1 * Density in ppg and pcf * Specific gravity * Pressure gradient in PSI/1000ft) The balance uses the cantilever design (fixed somewhere on the lever arm). The cup is attached to one end and the counter weight on the other end. The lever arm is calibrated‚ the rider also acts as a counterweight and there is a level glass
