Problem 57HP

Compressors, Fans

How much power is needed to run the fan in Problem?

A 0.6-m-diameter household fan takes air in at 98 kPa, 20°C and delivers it at 105 kPa, 21°C with a velocity of 1.5 m/s (see Fig. P4.18). What are the mass flow rate (kg/s), the inlet velocity, and the outgoing volume flow rate in m3/s?

ANSWER:

Solution 57 HP

Step 1 of 5:

In this question ,we need to find power required to run the fan, and also find mass flow rate, inlet velocity and the outgoing volume flow in ${m}^{3}/s$

Data given

Diameter of fan $d=0.6\ m$

Radius $r=\frac{d}{2}=\frac{0.6}{2}=0.3\ m$

Inlet pressure ${P}_{i}=98\ kPa$

Inlet temperature ${T}_{i}=2{0}^{0}C=290\ K$

Exit pressure ${P}_{i}=105\ kPa$

Exit temperature ${T}_{e}=2{1}^{0}C=294\ K$

Exit velocity ${V}_{e}=1.5\ m/s$
