**DuctRoundedInlet_CL**

Returns the pressure drop associated with a rounded inlet given the fluid, its flow rate and state, the radius of the inlet and the diameter of the pipe. Valid for circular duct cross-sections. This function calls the K_Rounded_Pipe_Inlet function from the minor loss library.

DELTAP = **DuctRoundedInlet_CL**(F$, m_dot, T, P, r, D)

**Inputs:**

F$: fluid string identifier

m_dot: mass flow rate (kg/s, lbm/hr)

T: inlet temperature (K, C, F, or R)

P: inlet pressure (bar, atm, Pa, kPa, or MPa)

r: radius of inlet (m or ft)

D: downstream duct diameter (m or ft)

**Output:**

DELTAP: pressure drop (bar, atm, Pa kPa, or MPa)

**Example: **

$UnitSystem SI Mass J K Pa Degree

$Load Component Library

$VarInfo DP units=Pa

m_dot = 0.2 [kg/s]

T = 300 [K]

P = 100e3 [Pa]

r = 0.05 [m]

D = 0.1 [m]

F$ = 'Air'

DP = **DuctRoundedInlet_CL**(F$, m_dot, T, P, r, D)

{**Solution:**

DP = 14.22 [Pa]}
