TDS = 0.5 Conductivity. This relationship holds good at low TDS. At high TDS values, TDS = 0.9 (slope of line) × electrical conductivity.

Many autoclaves are used to sterilize equipment and supplies by subjecting m to high-pressure saturated steam at 121 °C (249 °F) for around 15?20 minutes depending on size of load and contents.

Diaphragm valves are used to control flow by a movement a diaphragm. Upstream pressure, downstream pressure, or an external source can be used to change position of diaphragm.

Globe valves are only ones which can be used for 90 degree change in direction of flow. Specifically angle- globe valves are used for that purpose. Globe valves are not used for controlling pressure.

Chlorine is used to remove bacteria from water. The free chlorine in water should not exceed 2 mg/L. In surface water, chloride level is around 10 mg/L.

Wastewater contains 99.9% water and 0.1% solids. The goal is to remove this 0.1% of solids. Wastewater is water generated by industries and communities.

The ratio of discharge pressure to that of suction pressure is known as specific ratio. This is 1.1-1.2 for blowers. It is is>1.2 for compressors and <1.1 for fans.

BOD5 is oxygen equivalent of organic matter. It is determined by measuring dissolved oxygen used by microorganisms during biochemical oxidation of organic matter in 5 days at 20?C.

Blowers create air low. The blower system creates pressure through resistance to air flow. By combining flow rate and back pressure, actual operating air flow can be identified.

The sterilization temperature for high pressure sterilizer of a rectangular model is 121?C. The operating temperature for high pressure sterilizer of rectangular model is 121?C to 135?C.
