Answer:
Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges.

Explanation:
Foundations of Education refers to a broadly-conceived field of educational and profoundly important academic and professional purpose unifies persons Education as a profession in remarks made in relation to the expertise has long been the foundation of free and open academic inquiry.Setting goals for schools and students is an important process. It helps to motivate people when there is something specific to aim for. It is also a good way to show the clear path to success. The principal should work with the teachers to develop a plan and mission for the school

Explanation:
Answer:
a) 15.37 mm
b)
c) 5.7186 W/m². K
d) 0.60 m
Explanation:
Given that :
The surface temperature = 130°C = ( 130+ 273 ) K = 473 K
suspended in quiescent air at 25°C = ( 25 + 273 ) K = 298 K
Atmospheric Pressure = 1 atm
The properties obtained from Table A - 4 include :
v =
k = 0.03 W/m K
Pr = 0.700
η = 5
Hence, the boundary layer thickness at a location 0.15 m measured from the lower edge is 15.37 mm
b) The maximum velocity in the boundary layer with f'(n) = 0.275
u = 0.3659 m/s
the maximum velocity in the boundary layer at this location is 0.3659 m/s
the position in the boundary layer where the maximum occur is calculated as:
3.074 mm
c) Using the similarity solution result, , determine the heat transfer coefficient 0.15 m from the lower edge.
we know that:
=
= 28.593
Making the subject from the above formula:
= 5.7186 W/m². K
d) to determine the location on the plate that the boundary layer we become turbulent ; we have the following:
0.60 m
