why we messure differential pressure in pascle,mmhg,mmwc like different units in different company..

Answer / sbaskar

All are different units of pressure only.We use pascal,mmwc,orkg/cm2 for our convenience only.For instance if the pressure drop is minimum we use mmwc as it can be viewed easily using a watertube manometer instead of a pressure gauge.

Water flows through a pipe with circular cross sectional area at the rate of V / t = 80 L / s where V is the volume and t is time. Let Av = 80 L / s where A is cross sectional area and v is velocity of fluid. For point 1, the radius of the pipe is 16 cm. For point 2, the radius of the pipe is 8 cm. Find (a) the velocity at point 1; (b) the velocity at point 2; (c) the pressure at point 2 by using Bernoulli’s equation where P Rgy 0.5 RV = constant. P is the pressure, R = density of fluid, V = square of fluid’s velocity, g = gravitational constant of 9.81 N / kg and y = 2 m = difference of height at 2 points. The pressure of point 1 is 180 kPa.
