Fluid-mechanics Questions Set 59:
Determine the weight density of a liquid with a density of 950 kg/m³.
Solution:
With increase of temperature, viscosity of a fluid
Solution:
Water flows through a pipe having an inner radius of 10 mm at the rate of 36 kg/hr at 25°C. The viscosity of water at 25°C is 0.001 kg/ms. The Reynolds number of the flow is
Solution:
A soap bubble with radius of 5 m is given. The surface tension S of the soap solution is 3.5 × 10-2 N/m. What is the pressure difference in the soap bubble?
Solution:
What is the relation between the speed (N) of a centrifugal pump impeller and the pump's discharge?
Solution:
The total energy head of a particle moving in a fluid flow is identified as?
Solution:
Which of the following terms in fluid mechanics and thermodynamics refers to the temperature at a stagnation point in the flow of fluids?
Solution:
If a tank with a height of 5 meters is filled completely with water, what will be the pressure of the fluid at the bottom of the tank, assuming the fluid is at rest? (Take g = 9.81 m/s² and ρ = 1000 kg/m³ for the density of water.)
Solution:
We have been given a pump that is used to discharge liquid into a drum at the rate of 0.048 m³/s. The drum has a diameter of 1.60 m, a length of 4.50 m, and it can hold 4000 kg of the liquid. Calculate the mass flow rate of the liquid that is handled by the pump.
Solution:
A pitot static tube placed in the center of a 20 cm diameter pipeline has one orifice pointing upstream and the other perpendicular to it. If the pressure difference between the two orifices is 4.0 cm of water, calculate the coefficient of the pitot tube when the minimum discharge through the pipe is 1300 liters/minute. Assume the mean velocity in the pipe is 0.83 of the central velocity.
