The measurement of a fluid’s resistance to flow is calledviscosity.Viscosity is the property of a fluid that describes how easily it can deform or move when subjected to a shear stress, such as the force exerted by a pipe wall or a pump1. A fluid with high viscosity, such as honey, resists flow and requires more pressure to overcome the friction between its layers.A fluid with low viscosity, such as water, flows easily and has less frictional resistance2.Viscosity affects the hydraulic properties of water for fire protection systems, such as the flow rate, pressure loss, and pump power3. Viscosity is usually expressed in units of pascal-second (Pa s) or centipoise (cP) for liquids, and is dependent on the temperature and composition of the fluid.References:

79% of fire departments surveyed participate in the delivery of emergency medical services (EMS).This is based on the NFPA report “US Fire Department Profile 2020”1, which states that nationwide, 37% of fire departments provided no EMS, 46% provided basic life support (BLS), and 17% provided advanced life support (ALS). Therefore, the percentage of fire departments that provided either BLS or ALS is 46% + 17% = 63%. However, this does not include fire departments that provided EMS through a third-party contract or agreement.According to the NFPA fire service survey from 2018–20202, 16% of fire departments reported having such an arrangement. Therefore, the percentage of fire departments that participated in the delivery of EMS in some form is 63% + 16% = 79%.References:

In the plastics industry, the four broad areas of processing arepolymerization,conversion,finishing, andrecycling1.Polymerization is the process of creating plastic resins from monomers or pre-polymers, using chemical reactions such as addition, condensation, or ring-opening2.Conversion is the process of transforming plastic resins into plastic products, using various methods such as injection molding, blow molding, extrusion, rotational molding, and thermoforming3.Finishing is the process of adding value to plastic products, such as coating, printing, welding, or assembling4.Recycling is the process of recovering plastic waste and converting it into new plastic products or raw materials, using mechanical, chemical, or biological methods5. Therefore,manufacturingis not one of the four broad areas of processing in the plastics industry, as it is a general term that encompasses all the stages of producing plastic products from raw materials.References:
