ME308: Bernoulli's, Energy Equation, RTT, Linear Impulse and (Midterm 2)

The work done

in the following bernoulli’s equations

bernoulli’s represents c.o.e

B.E should apply to a streamline

continuity equation

bernoulli’s principle

BE Newtons second law

3 forms of be

all forms apply to streamline

False

dynamic represents ke

static pressure represents pressure energy

flow measurment devic

wings generate lift force

stagnation point, ke converted to pressure energy

pressure drops ventrui

reservoir, static pressure zero

work done increase ke

Statement A

The problem is to estimate the pressure at location A

86.4 Pa

problem is to estimate pressure at location B.

-108 pa gage

horizontal pipe carries cooling water for thermal power plant

pressure at point 2 is 418 kpa

a pipe 50 cm in diameter. what power must be supplied.

rtt control and system volume applied

mass flow rate if not considering imcompressibility

i=0

i represents intensive property

represents mass flow rate

steady and control volume, rtt becomes continuity equation
