For the following questions answer them individually
A right-circular cylinder open at top is filled with water and rotated about its vertical axis at such speed that half the water spills out. What is the value of pressure at centre of the bottom?
At a point on a streamline, the velocity is 3 m/sec and the radius of curvature is 9 m. If the rate of increase of velocity along the streamline at this point is $$\frac{1}{3}$$ m/sec/m, then the total acceleration at this point would be _____
For Newtonian fluid behaviour, the shear stress exerted by the fluid is equal to the _____.
Which of the following are the advantages of impulse turbine over reaction turbines ?
A: Occupies less space per unit power
B: Compounding is not necessary for speed reduction as the rotor speeds are usually low.
C. Suitable for high power generation.
According to Bernoulli's principle in fluid dynamics, for inviscid flow, increase in speed of fluid leads to which of the following?
