Question

The pressure in a section of horizontal pipe with a diameter of 24 mm is 147 kPa. Water flows through this section at 6.3 m/s. The pressure is to be reduced to 106 kPa by constricting the pipe. What should the diameter of the constricted section be?

I dont understand these questions.

3. The pressure in a section of horizontal pipe with a diameter of 24 mm is 147 kPa. Water flows through this section at 6.3 m/s. The pressure is to be reduced to 106 kPa by constricting the pipe. What should the diameter of the constricted section be? a) 21.9 mm b) 18.1 mm c) 16.8 mm d) 28.7 mm e) 24.2 mm 4. A charge of 4.00 uC is placed at each corner of a square 0.100 m on a side. Determine the magnitude of the force on each charge a) 52.1 N b) 15.4 N c)43.0N d) 34.8N e) 27.5 N 5. Determine the magnitude of the electric field at the point P shown in the figure. The two charges, +2.00 nC and -2.00 nC, are separated by a distance of 2a, where a is 1.00 mm. Point P is on the perpendicular bisector of the line joining the charges, a distance x1.00 m from the midpoint between them. a) 1.08x101 N/C d) 1.44x101 NIC c) 2.65x102 N/C b) 3.60x10 NIC e) 7.19x102 NIC
