Pressure Drop for Chilled water tank (buffer Vessel)
Pressure Drop for Chilled water tank (buffer Vessel)
(OP)
For the emergency supply to critical load, we have installed a buffer vessel of the following details.
Dimension: 1500 dia x 3800 length. (60"x152")
Volume : 7.186 m3 (with distance head 200mm)
Mounting: Horizontal Type.
Material: Carbon Steel. A-106-GR.B
Inlet/Outlet: 150 Dia. PN16 Flanges.
Installed at the suction of the two pumps along with a pressurisation unit and a PHEX .
The total flow rate along the header 15 l/s.
My question is how to calculate the pressure drop across the tank?

That being said, there will be pressure losses at the inlet and outlet to the tank. The magnitude of the loss will depend on the connection detail. Most fundamental fluid mechanics textbooks will have loss coefficients for various inlets or exits. The equipment supplier should also be able to provide that information for you.

Equivalent lenght=K (v2/2g)
Where K for sharp edges entries is .50
