Answer:

Explanation:
Data given
temperature =700c
Density=10.35g/cm^3
but

Nv is the number of vacant site and N is the number of lattice site.
Since the number of lattice site can also b computed as

if we substitute the value of the number of lattice into the first equation, we arrive at

Answer:
The total hole mobility is 41.67 cm²/V s
Explanation:
Data given by the exercise:
hole mobility due to lattice scattering = ul = 50 cm²/V s
hole mobility due to ionized impurity = ui = 250 cm²/V s
The total mobility is equal:

Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy by the use of centrifugal force acting on the fluid. These are the most popular and commonly used type of pumps for the transfer of fluids from low level to high level.
