How is heat transferred from the heating element to the water at the bottom of the kettle? The animation below shows heat transfer by convection in a kettle. The water molecules at the bottom of the kettle gain heat energy from the flame and vibrate faster and move further apart. The colder less dense molecules […]
What is the use of kinematic viscosity?
What is the use of kinematic viscosity? Kinematic viscosity is a measure of a fluid’s internal resistance to flow under gravitational forces. It is determined by measuring the time in seconds, required for a fixed volume of fluid to flow a known distance by gravity through a capillary within a calibrated viscometer at a closely […]

What is the meaning of sparse matrix?
What is the meaning of sparse matrix? A sparse matrix is a matrix that is comprised of mostly zero values. Sparse matrices are distinct from matrices with mostly non-zero values, which are referred to as dense matrices. The example has 13 zero values of the 18 elements in the matrix, giving this matrix a sparsity […]
Which procedure is used when manually bleeding a brake system?
Which procedure is used when manually bleeding a brake system? Manual bleeding is the most commonly used method. The master cylinder and brake pedal are used as a pump to cause fluid to flow through an open bleeder screw. This fluid flow should flush air out. Manual bleeding should be performed smoothly so as not […]
