Armstrong International Interview Questions and Answers

Rankine cycle is a thermodynamic cycle used in steam power plants to generate electricity.

• Rankine cycle is a thermodynamic cycle that converts heat into work using steam as the working fluid.

• Reheat Rankine cycle involves reheating the steam in between stages to increase efficiency.

• Regenerative Rankine cycle involves extracting steam from the turbine at various stages to preheat the feedwater.

• P-V diagram for Rankine cycle consists of four main processes: isentropic compression...read more

Angle of projection is the angle at which an object is launched into the air.

• Angle of projection affects the range and height of the projectile.

• It is measured from the horizontal axis.

• The optimal angle of projection for maximum range is 45 degrees.

• The formula to calculate the range is R = (v^2 * sin(2θ)) / g, where v is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity.

• The formula to calculate the maximum height is H = (v^2 * sin^2(θ...read more

Thermodynamic systems are physical systems that exchange energy with their surroundings.

• A thermodynamic system can be open, closed, or isolated.

• Examples of thermodynamic systems include a gas in a container, a steam engine, and a refrigerator.

• Thermodynamic systems can exchange energy in the form of heat and work.
