Explanation Given: The height of the wall ( h ) is 12 ft. The length of the wall ( l ) is 12 ft. The width of the wall ( w ) is 12 ft. Calculation: Calculate the intensity of the horizontal distributed load at B . w = γ w ⋅ h ⋅ b w = 62.4 lb/ft 3 × 12 ft × 8 ft =5990 .4 lb/ft Calculate the horizontal force ( F h ) . F h = 1 2 w h = 1 2 × 5990.4 lb/ft × 12 ft =35942 .4 lb Draw the free body diagram of the parabolic shaped wall as shown in figure (1). The weight of the water container in the block is equal to vertical force acting on the wall. Calculate the volume of the water column. V = 2 3 ( h × l × w ) V = 2 3 × 12 ft × 12 ft × 8 ft =768 ft 3 Calculate the vertical force ( F V )

Consider 0.65 kg of N2 at 300 K, 1 bar contained in a rigid tank connected by a valve to another rigid tank holding 0.3 kg of CO2 at 300 K, 1 bar. The valve is opened and gases are allowed to mix, achieving an equilibrium state at 290 K. Determine: (a) the volume of each tank, in m³. (b) the final pressure, in bar. (c) the magnitude of the heat transfer to or from the gases during the process, in kJ. (d) the entropy change of each gas and of the overall system, in kJ/K.
