How do you perform a hardness test? A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter. How […]
What do solenoids and electromagnets have in common?
What do solenoids and electromagnets have in common? Both solenoids and electromagnets use electric current and coiled wires to produce strong magnetic fields. Solenoids – by running current through a wire which is wound into many loops, you strengthen the magnetic field in the center of the coil. A coil of wire with a current […]
What is the main difference between a latch and a flip flop?
What is the main difference between a latch and a flip flop? The difference between a latch and a flip-flop is that a latch is level-triggered (outputs can change as soon as the inputs changes) and Flip-Flop is edge-triggered (only changes state when a control signal goes from high to low or low to high). […]

How do you calculate mass flow from velocity?
How do you calculate mass flow from velocity? Alternative equations Mass flow rate can be calculated by multiplying the volume flow rate by the mass density of the fluid, ρ. The volume flow rate is calculated by multiplying the flow velocity of the mass elements, v, by the cross-sectional vector area, A. What is the […]
