Draft is a difference in pressure that causes _______

Quesiton : Draft is a difference in pressure that causes _______

Answer: air or gasses to flow

Draft is a difference in pressure that causes _______ The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow. How can the answer be improved? Draft is the difference in pressure between two areas that causes air or gases of combustion to flow. True Gases move from an area of … Cause for the stack effect. There is a pressure difference between the outside air and the air inside the building caused by the difference in temperature between the outside air and the inside air. That pressure difference ( ΔP) is the driving force for the stack effect and it can be calculated with the equations presented below. Draft is a difference in pressure that causes _____ air or gasses to flow When blowing down a boiler with a quick opening and a screw type valve the … When the furnace draft is maintained at or just below atmospheric pressure by use of a combination of forced and induced draft fans the draft is referred to as a _____ draft system. Balanced __________ draft is the difference in pressure created solely by the stack or chimney. Air flow - volume and velocity - due to stack or flue effect caused by indoor hot and outdoor cold temperature difference The temperature difference between the outside air and the inside air creates a "natural draft " forcing air to flow through the building. The direction of the air flow depends on ... The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to the difference in pressure in the combustion chamber area which results in … When a pressure difference between two points exists within a fluid and is not balanced out by the internal forces acting on the body the fluid start to move from the higher pressure point to the low pressure point to minimize the pressure difference. This continuous movement of the fluid is known as flow. Draft is the pressure difference that is available to drive the flow of air and/or combustion gases through an appliance and its venting system. All combustion systems that are vented by natural chimney draft depend on the temperature difference that is maintained between the gases in the flue and the outdoor air for proper operation. The operation of the draft -inducer motor causes a large drop in air pressure on the exhaust side of the pressure switch while a smaller drop occurs on the intake side. If the difference between the two is great enough a flexible diaphragm inside the pressure switch moves and completes a circuit allowing ignition. Thermal Power Plants: What is a negative DRAFT ? Update Cancel. ad by Zoho. ... Draft can also be referred to the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow. ... This causes combustion gases to be sucked into the stack and combustion air to be drawn into the furnace ...
