Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).Basic Mine Ventilation,open crosscut, in return air or located within 150 feet of pillar workings or longwall faces must be maintained in permissible condition Air always flows from a point of higher to lower pressure. * Blowing fans create a high pressure point immediately inby the fan. Air travels from this high point through the mine to the surface.Air Flow, Air Systems, Pressure, and Fan Performance,To balance the system by design increase the air flow rate in Section 1 to bring it up to the higher pressure loss of Section 2. To correct the air flow rate for Section 1 use the Fan Laws: Q 1 new = Q 1 old * (P t loss 1 new/ P t loss 1 old)1/2. Q 1 new = 4000 * (1.192/1.165)1/2 = 4046 cfm.Schematic diagram of a typical AHU system. | Download,,Fig. 1 illustrates the schematic diagram of such an AHU system.

13-08-2021· A schematic diagram is a visual representation of a project plan that is prepared using lines and generic icons to keep the drawing extremely simple and easily understandable. Although schematic diagrams are usually prepared for electrical and electronic projects, they are not limited to those domains and can be created for many other industries such as buildingPneumatic circuit diagrams – Learnchannel-TV,The structure of pneumatic schematics. In pneumatic circuit diagrams, the components are arranged the way that the flow of energy always flows from the bottom up (as opposed to electrical schematics).Thus the pressure source represents the first element, the actuator, the last element. In purely pneumatic circuits the processing of the input signals is also performedPneumatic, Hydraulic and P&ID Diagrams,Inserting Hydraulic Schematic Symbols The hydraulic symbol library in AutoCAD® Electrical includes filters, valves, cylinders, pressure switches, motors, pumps, meters, restrictors, quick disconnects, flow arrows and more.

But the faster the air flow and the less aerodynamic the object, the more the air flow breaks away and becomes turbulent. That's what we mean by form drag.
