According to Bernoulli's theorem the pressure of water should remain uniform in a pipe of uniform radius. But actually it goes on decreasing, why is it so?

Ac cording to Bernoulli's theorem the pressure of water should remain uniform in a pipe of uniform radius. But actually it goes on decreasing, why is it so?

Ac cording to Bernoulli's theorem for the streamline flow of an ideal liquid, the sum of pressure energy/mass, kinetic energy/mass and potential energy /mass remains constant at every cross section, throughout the liquid flow. i.e., (P)/(rho) + (1)/(2)upsilon^2 + gh = cosntant, where the symbols have their usual meaning. Note that an ideal liquied is the one, which is perfectly incompressible, irrotational and non visous. Read the above passage and answer the following question ? (i) At what speed will the velocity head of a stream of water be equal to 40 cm ? (ii) What is the implication of Bernoulli's theorem in day to day life ?

Why should the potentiometer wire be of uniform cross-section and composition ?

The bulk modulus of a spherical object is B if it is subjected to uniform pressure p , the fractional decrease in radius is:

Assertion: The velocity of flow of a liquid is smaller when pressure is larger and viceversa. Reason: According to Bernoulli's theorem, for the stream line flow of an ideal liquid, the totla energy per unit mass remains constant.

As the radius of the orbit goes on decreasing the electrons should emit a radiation of

Why should the area of cross-section of the meter-bridge wire be uniform ? Explian
