Question

Air flows at the rate of 1.5 m3/s1.5\text{ m}^3/\text{s} through a horizontal pipe with a gradually reducing cross-section as shown in the figure. The two cross-sections of the pipe have diameters of 400 mm400\text{ mm} and 200 mm200\text{ mm}. Take the air density as 1.2 kg/m31.2\text{ kg}/\text{m}^3 and assume inviscid incompressible flow. The change in pressure (p2−p1)(p_2 - p_1) (in kPa) between sections 1 and 2 is
A horizontal pipe with air flow, showing section 1 with diameter 400 mm and section 2 with diameter 200 mm.
