Pressure loss at Suction.

In case of an abrupt suction opening, the air is accelerated as it
approaches the opening, forming a vena contracta inside the duct. The area changes from infinity to the duct area. In such a case, the loss coefficient C is taken as 0.85. By making a flanged entrance, the loss coefficient is reduced to 0.34. The loss coefficient can be further reduced to 0.03 by making the formed entrance of bell-mouth shape
