problem 40 with parts
40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...

An atmospheric column between the pressure levels 90 and 50 kPa is initially isothermal. The geostrophic wind is 10 m / s and south at 90 kPa, 10 m / s and west at 70 kPa, and 20 m / s and west at 50 kPa. Note: It is assumed that the vertical cooling rate is linear between 90 and 50 kPa and that the thickness of the layer 80 - 60 kPa is constant and equal to 2.25 km....

1. Consider a hydraulic system with two pistons. Piston 1 applies a force F, over area A, and piston 2 applies a force F over area Ay. If you double the force applied by piston 1 and reduce the area of piston 2 by a factor of 3, what is the new force in terms of the original force F? 2. A piston that is part of a hydraulic system has a surface area of 0.025 square meters. The hydraulic...
Air flows through a constant area duct. The pressure and temperature of the air at the...
Air flows through a constant area duct. The pressure and temperature of the air at the inlet to the duct are P1 = 100 kPa absolute, and T1 = 298 K, respectively. Inlet Mach number is M1 = 0.1. Heat is transferred to the air as it flows through the duct and as a result the Mach number at the exit increases. a) Find the pressure and temperature at the exit, while the exit Mach number changes between M=0.2 to...

Draw a picture. Show open surfaces, pistons, boundaries, and other features that affect the pressure. Include height and area measurements and fluid densities. Identify the points at which you need to find the pressure. These objects make up the system; the environment is everything else. Determine the pressure at the various surfaces. For a surface open to the air, p0=patmos, usually 1 atm. For a surface covered by a gas, p0=pgas. For a closed surface, p=F/A, where F is the...
