Question

) A container has a vertical tube, whose inner radius is 24.00 mm, connected to it at its side, as shown in the figure. An unknown liquid reaches level A in the container and level B in the tube–level A being 5.0 cm higher than level B. The liquid supports a 20-cm high column of oil, between levels B and C, whose density is The mass of the oil is closest to

Answer #1

A cylindrical tube that is 2.50 mm long and has a radius of 150
mmmm is filled with water. It is oriented with its long central
axis vertical, and it is open to the air at the upper end. A hole
80.0 mmmm in radius is drilled in the bottom, and the water is
allowed to drain out.
a) When the water level is half the height of the tube what is
the speed of the water exiting though the...

A long, clear, flexible tube is bent into a U shape(open at both
ends), and we pour water into it (density 1000 kg/m3)until the
water reaches the same level on both vertical sides. Now we pour a
7 cm column of mercury into the left
side(density 13,600 kg/m3), which does not mix with the water.
(a)When the fluids reach equilibrium, find the difference in
elevation between the top of the mercury (on the left) and the top
of the water...

1) A mercury barometer has a radius of 7 mm. The
density of the mercury is 13.6 g/cm^3, the superficial tension of
the mercury is 465 dyn/cm and the angle between the mercury and the
glass of the vertical tube that contains it is 140°. What is the
height of the level of the mercury in the glass tube?
2) A bar made of steel is 1 m long and has a radius of
5 cm. If the bar is...

a) A vertical plate of 700 mm wide
and 120 cm height is maintained at a temperature of 95oC
in a room at 25oC with an air conditioning with velocity
of 36000 cm/min. Calculate the heat transfer coefficient and
convective heat transfer rate.
(b) Two concentric cylinders are
located in a large room. Determine the view factors for the two
cylinders when the length is 20 cm, the inner radius
(r1) is 5 cm and the outer radius (r2) 10...

PLEASE DO NOT OMIT STEPS, EXPLAIN IT DETAILED MIND PLEASE, ALSO
WRITE BIG SO THAT I CAN LOOK AT IT AS I CAN CONFUSE THANK YOU VERY
MUCH!
APART OF RESOLVING IT IF YOU CAN SAY ME BECAUSE WHEN DOING THE
JOURNEY OF THE PRESSURE OF THE DUCT TOWARDS THE ATMOSPHERIC
PRESSURE, IS THE PRESSURE OF THE AIR DESPRECIATED?
When measuring small temperature differences with a manometer,
one of its branches is inclined, to improve the accuracy of the
measurement....

Water moves through a constricted pipe in steady, ideal flow. At
the lower point shown in the figure below, the pressure is 1.65 ✕
105 Pa and the pipe radius is 2.80 cm. At the higher point located
at y = 2.50 m, the pressure is 1.27 ✕ 105 Pa and the pipe radius is
1.30 cm. (a) Find the speed of flow in the lower section. m/s (b)
Find the speed of flow in the upper section. m/s (c)...
