Determine the throat diameter of a venturi-meter in an installation of 100 mm diameter pipe carrying water. the maximum range available in water-hg differential pressure gauge is 50 cm of hg deflection. find the maximum throat diameter which will induce full gauge deflection when the flow rate is 20 /s. assume cd0.984.

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
