Answer:
Plumbing using a one-way check valve to stop water flowing back on a pump when the pump shuts off.
Explanation:
Diodes are like check valves, keeping current from flowing both ways. Used to create d.c. out of a.c by rectification. Also to block flow if d.c. power like a battery is hooked up in reverse polarity.
Answer:Mechanical Engineers
Explanation: Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches.
Answer:
Explanation:
Given.
Thickness of brass plate
Thermal conductivity of brass
Density of brass
Specific heat of brass
Thermal diffusivity of brass
Temperature of oven
The initial temperature
Plate remain in the oven
Heat conduction in the plate is one-dimensional since the plate is large relative to its thickness and there is thermal symmetry about the center plane.
The thermal properties of the plate are constant.
The heat transfer coefficient is constant and uniform over the entire surface.
The Fourier number is > 0.2 so that the one-term approximate solutions (or the transient temperature charts) are applicable (this assumption will be verified).
The Biot number for this process
The constants and corresponding to this Biot are, from 11-2 tables.
The interpolation method used to find the
and
The Fourier number
Therefore, the one-term approximate solution (or the transient temperature charts) is applicable.
Then the temperature at the surface of the plates becomes
