How does adjusting the gas needle valve on the Bunsen burner affect the flame?
Adjusting the gas needle valve controls the flow rate of gas entering the burner. Decreasing the gas flow by turning the needle valve counterclockwise results in a smaller, bluer flame with less heat, while increasing the gas flow by turning the needle valve clockwise produces a larger, yellower flame with more heat.
What is the relationship between the ideal gas law and the mass flow rate?
The ideal gas law relates the pressure, volume, and temperature of a gas. The mass flow rate is the amount of mass passing through a given area per unit of time. The ideal gas law can be used to calculate the mass flow rate of a gas by considering the pressure, volume, temperature, and molar mass of the gas.
What is internal friction of a gas?
Internal friction in a gas is the resistance to flow that occurs within the gas itself. It arises due to interactions between gas molecules as they move past each other, causing energy loss in the form of heat. Internal friction can affect the overall flow characteristics and behavior of a gas.
Which types of heat transfer invlove heat flow from objects to colder objects?
Conduction, convection, and radiation are all types of heat transfer that involve heat flow from objects to colder objects. Conduction is the transfer of heat through a material due to direct contact, convection is the transfer of heat through a fluid (liquid or gas), and radiation is the transfer of heat through electromagnetic waves.
What forms when a gas or liquid transfers heat as it moves?
Convection occurs when heat is transferred through the movement of a gas or liquid. This movement causes less dense, warmer fluid to rise and denser, cooler fluid to sink, creating a continuous flow of heat transfer.

How do you calculate the output of a gas fire?
To calculate the output of a gas fire, you need to know the heat input rating of the gas fire in British thermal units per hour (BTU/hr) or kilowatts (kW). The heat output is typically a percentage of the heat input, commonly around 70-90%. You can calculate the heat output by multiplying the heat input by the efficiency percentage (e.g. heat output = heat input x efficiency percentage).
How do you calculate heat rate in gas power plant?
E=MC2 + o2 + H20 = Heat rate

How do you calculate the flue gas velocity in airpreheater?
To calculate the flue gas velocity in an air preheater, you would need to know the volumetric flow rate of the flue gas passing through the preheater and the cross-sectional area of the preheater. You can then use the formula: Velocity = Volumetric flow rate / Cross-sectional area of preheater. This calculation will give you the velocity at which the flue gas is moving through the air preheater.
How do you calculate heat input and traveling speed for gas metal arc welding?
Heat input= voltage x current x 60 \ ipm
What is the function of the gas tap in Bunsen burner?
The gas tap in a Bunsen burner controls the flow of gas to the burner. By adjusting the gas tap, you can regulate the flame intensity, controlling the amount of heat produced. Turning the tap on allows gas to flow to the burner, while turning it off shuts off the gas supply.
