ES 202 Fluid and Thermal Systems Lecture 4: Pressure Distributions on Submerged Surface (12/09/2002). Assignments. Reading: Mechanics: definition of center of mass, moment of inertia Cengel & Turner Section 5-4 ES 201 notes Homework: 10-11, 10-19, 10-37 in Cengel & Turner.
yp = yc + Ixx,c / yc Awhere yc is the location of centroid and
Ixx,c / yc Ais the downward shift of center of pressure relative to centroid
the hydrostatic pressure increases/decreases____________ with depth;
the pressure gradient (rate of change) depends on the ____________ of the fluid.
Something about manometer:
A manometer is a device which measure small pressure difference based on the difference in ____________ between fluid columns
For a given pressure difference, the difference in height between the fluid columns will be greater if a fluid of lower/higher density is used.
The pressure equation:
P2 = P1 +/- r g h
describes the pressure variation in a manometer. The minus (-) sign is used when Point 2 lies above/below Point 1 and vice versa.Quiz on Lecture 3
If one of the sides of the fish tank is slightly sloped at 30o, how will the followings be different?
If the slope is replaced by a
What do you expect the results to be?
