Part-1 The water level in a tank is 15 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end of the hose is pointed straight up. The tank cover is airtight, and the air pressure above the water surface is 3 atm gage. The system is at sea level. Determine the maximum height to which the water stream could rise. Part-2 Water at 15°C (? = 999.1 kg/m³ and ? = 1.138 x 10?³ kg/m·s) is flowing steadily in a 30-m-long and 5-cm-diameter horizontal pipe made of stainless steel at a rate of 9 L/s. Determine (a) the pressure drop (b) the head loss (c) the pumping power requirement to overcome this pressure drop.

Water Flowing from a Tank Water flows steadily from an open tank as shown in the figure (Figure 1). The elevation of point 1 is 10.0 m, and the elevation of points 2 and 3 is 2.00 m. The cross-sectional area at point 2 is 4.80×10^(-2) m^2; at point 3, where the water is discharged, it is 1.60×10^(-2) m^2. The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe. Assuming that Bernoulli's equation applies, compute the volume of water ΔV that flows across the exit of the pipe in 1.00 s. In other words, find the discharge rate ΔV/Δt. Express your answer numerically in cubic meters per second. ΔV/Δt = 0.200 m^3/s What is the gauge pressure pgauge at point 2? Express your answer numerically in pascals. pgauge =
