Carbon dioxide at 200 kPa, 10°C flows at 1 kg/s in a 0.25-m2 cross-sectional area pipe. Find the velocity and the volume flow rate.

Billy flew from New York to Cincinnati and had a closed container with a closed outlet to drink from. The container has a diameter of (D. = 5 cm) and height of (H. = 27 cm). The container is filled with 72% of water. The container's outlet has a diameter of (D. = 1 cm) and height of (H, = 30 cm). Last moment container was opened was in New York at an atmospheric pressure of 1072 hPA. When Billy landed in Cincinnati the atmospheric pressure was 850. When Billy opened the bottle once again water discharged because of difference in pressure. 1. Calculate instantaneous flow rate at the point when the closed containers outlet was opened. Assume pressure in the closed container is the difference between cities = 222 hPa and air pressure in Cincinnati 0. Figure 1: Do = Icm Ho = 30 cm %3D 27 = H. Cm Hw Dc =5 Cm

Q4) The nozzles receive steam at 1.75 MPa, 300 °C, and exit pressure of steam is 1.05 MPa. If there are 16 nozzles, find the cross-sectional area of the exit of each nozzle for a total discharge to be 280 kg/min. Assume nozzle efficiency of 90%. If the steam has velocity of 120 m/s at the entry to the nozzles, by how much would the discharge be increased?

steam having enthalpy 2930.8 KJ/ kg, enters a nozzle with a velocity of 60 m/s. find the velocity of steam at the exist of the nozzle, if its enthalpy is reduced to 2721.4 kj/kg
