A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke .
There are three types of cokers used in oil refineries: delayed coker, fluid coker and flexicoker. [2] [3] The one that is by far the most commonly used is the delayed coker. The schematic flow diagram below depicts a typical delayed coker: A typical schematic flow diagram of a delayed coking unit
A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s , e.g. water.
In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.

In 1966, Rockwell invented the world's first power miter saw. In 1981, Rockwell's power tool group was acquired by Pentair and re-branded Delta Machinery. Pentair's Tools group was acquired by Black & Decker in 2005. [5] Since 2011, Delta has been a subsidiary of Chang Type Industrial Co., Ltd. of China.
