A U-tube having horizontal arm of length 20 cm, has uniform cross-sectional area`=1cm^(2)`, It is filled with water of volume 60 cc. What volume of a liquid of density `4g//cc` should be poured from one side into the U-tube so that no water is left in the horizontal arm of the tube?

A

`60c c`

B

`45c c`

C

`50c c`

D

`35c c`

Text Solution

Verified by Experts

The correct Answer is:
D

`hrhog=60xx1xxg`
`h=15cm`
volume `=(15+20)xx1=35 c c`.

A U - tube having a horizontal arm of length 20 cm, has a uniform cross - sectional area 1cm^(2) . It is filled with water of volume 60 cc. The volume of a liquid of density "4 g cc"^(-1) required to be poured in one arm of the U - tube so that no water is left in the horizontal arm of the tube is ("take g "=9.8 ms^(-2))

Length of horizontal arm of a uniform cross section U -tube is l= 21 cm and ends of both of the vertical arms are open to surrounding of pressure 10500 N//m^(2) . A liquid of density rho = 10^(3) kg//m^(3) is poured into the tube such that liquid just fills the horizontal part of the tube. Now one of the open ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm With angular velocity omega_(0) = 10 rad//s . If length of each vertical arm is a = 6 cm , calculate the length of air column in the sealed arm. (in cm)

Length of the horizontal arm of a uniform cross - section U - tube is l = 5 cm and both ends of the vertical arms are open to the surrounding pressure of "7700 N m"^(-2) . A liquid of density rho=10^(3)" kg m"^(-3) is poured into the tube such that the liquid just fills the horizontal part of the tube. Now, one of the open ends is sealed and the tube. Now, one of the open ends is sealed and the tube is then rotaed about a vertical axis passing through the other veritcal arm with angular velocity omega due to which the liquid rises up to half the length of the vertical arm. If length of each vertical arm is a = 6 cm. What is the value of omega("in rad s"^(-1)) ?

A horizontal tube of uniform cross-sectional area A is bent in the form of U as shown in figure. If the liquid of density rho enters and leaves the tube with velcity v, then the extermal force F requried to hold the bend stationary is

A U tube pf uniform born of cross sectional area A has been set up vertically with open ends facing up Now m gm of a liquid of density d is poured into it. The column of liquid in this tube will oscillation with a period T such that

The plastic tube in Fig. has a cross-sectional area of 5.00 cm^(2) . The tube is filled with water until the short arm (of length d = 0.800 m) is full. Then the short arm is figure sealed and more water is gradually poured into the long arm. When the total height of water in the long arm reaches 2.80 m, the seal is on the verging of popping. What force is then on the seal?

The U-tube shown has uniform cross-section A liquid is filled in the two arms up to height h_(1) and h_(2) and then the liquid is allowed to move neglect viscosity and surface tension. When the levels equalize in the two arms, the liquid will
