What is difference between Medium velocity water spray system and High velocity water spray System?

Medium Velocity Water Spray Systems are installed to control the burning and to provide cooling and/or exposure protection to such risks where extinguishment is always not possible or even desirable e.g. fires involving flammable fluids having flash points below 650 C (1500 F). These 600 C systems are also used sometimes for power station applications in coal conveyors, cable galleries etc. High Velocity water spray systems are installed to extinguish fires involving liquids with flash points of 650 C (1500 F) or higher. Three principles of extinguishment are employed in the system - emulsification, cooling and smothering. The result of applying these principles is to extinguish the fire within a few seconds. For more details, attention is drawn to Section 6 of the Rules.
This section provides Rules and guidelines for the protection of the following.
a) Transformers, oil filled equipments of power stations
b) Turbo-alternators and other
c) Oil fired boiler rooms, oil quenching tanks.

Difference between pearmeability and permeability coefficient?
Permeability is part of the proportionality constant in Darcy `s law which relates discharge (flow rate) and fluid physical properties (e.g. viscosity), to a pressure gradient applied to the porous media:The proportionality constant specifically for the flow of water through a porous media is called the hydraulic conductivity; permeability is a portion of this, and is a property of the porous media only, not the fluid. Given the value of hydraulic conductivity for a subsurface system, k, the permeability can be calculated as:κ is the permeability, m2k is the hydraulic conductivity, m/sμ is the dynamic viscosity, kg/(m·s)ρ is the density of the fluid, kg/m3g is the acceleration due to gravity, m/s2.v is the superficial fluid flow velocity through the medium (i.e., the average velocity calculated as if the fluid were the only phase present in the porous medium)ΔP is the applied pressure difference (Pa)Δx is the thickness of the bed of the porous medium (m)

In physical science not biology what is the difference between a closed system and an open system?
A closed system does not allow for energy or matter to enter or leave the system.
What is the difference between high velocity and medium velocity water spray system in fire fighting?
The sprinkler head design. High velocity heads have longer nozzles with a venturi tube (a type of curved nozzle) which increases the velocity of the water spray. Medium velocity heads are shorter and do not use a venturi.

Difference between distributed system and multiprocessor system?
The difference between distributed system and multiprocessor system is whether the processing units in the system share the main memory. If yes, then the system is multiprocessor system; otherwise, it's a distributed system.
