A pump steadily delivers water through a hose terminated by a nozzle. The exit of the nozzle has a diameter of 0.6 cm and is loc

ated 10 m above the pump inlet pipe, which has a diameter of 1.2 cm. The pressure is equal to 1 bar at both the inlet and the exit, and the temperature is constant at 20C. The magnitude of the power input required by the pump is 1.5 kW, and the acceleration of gravity is g 9.81 m/s2 . Determine the mass flow rate delivered by the pump, in kg/s

Answer:

The highest pressure is located at points x & y.

Explanation:

The pressure will be greater at the X & y points, because they are at a deeper distance than the Z point. We must remember that the pressure is a function of the depth of the fluid, and is expressed by the following equation.

P = densi*g*h\\where\\densi = density [kg/m^3]\\g = gravity [m/s^2]\\h = elevation [m]

The pressure is always measured with respect to the liquid level towards the depth of the fluid, so at greater depth greater pressure

Why should your average experimental value actually only be express with a maximum of 2 significant digits?
Sonja [21]

Explanation:

Maximum two significant digits represents the number at the position 0.01. The experimental values are taken as only two significant digits is because after two digits the value can be neglected as these values are very small as compared to the whole number.

Thus, all the experimental values are represented by two significant digits.
