A pipe carrying oil of a specific gravity 0.877 changes in size from 150 mm at section 1 and 450 mm at section 2. Section 1 is 3.6 m below section 2 and the pressures are 90kPa and 60 kPa respectively. If the discharge is 150 L/s. Determine the head lost and the direction of flow.

2. Given H = 1.8 m & D = 0.2 m through the hole in the open top container. Determine the head losses through the tank outlet if the exit discharge were 0.163 m³/sec. H D

2. A discharge of 8.5 L/s of oil having a sg=0.8 occurs through the venturi shown. The diameter of the pipe is 37.5 mm while that of the throat is 25 mm. The liquid in the differential gage shown contains mercury sg = 13.6 and the rest is filled with oil 37.5 mm A) Find the velocity at the throat (7.7 m/s) B) Compute for the value of h1 (0.8125 m) C) Compute for the value of h2 (0.238 m) oil mercury 25 mm h1 37.5 mm h2

An ideal liquid flowing through a pipe A of cross-section 0.2m² with velocity 10m/s enters a T-junction. One side of the T-junction B has cross-section area 0.1m² and the other side Chascross-section area 0.05m². If the velocity of water in C is 15m/s then in B the velocity is
