1.	A pipe carrying water tapers from cross section 0.5 m2 at A to 0.2 m2 at B. The average velocity at A is 2 m/s and pressure is 500 kN/m2 (gauge). If the frictional losses are negligible, then pressure at B, which is 5 m above the level of A, would be (assume, gravity acceleration as 10 m/s2 and unit weight of water as 10 kN/m3:
A.	532 kN/m2
B.	405.5 kN/m2
C.	439.5 kN/m2
D.	388.2 kN/m2
Answer» D. 388.2 kN/m2
