Please help with the problem below and explain well, Im really struggling with understanding it. Thank you so much in advance! Commercial airliners cruise at about 10 km above sea level, where the air outside is mighty cold - let’s say -60°C. Nonetheless the airplane needs ventilating, with the plane does by taking in the outside air and compressing it. a. What is the temperature of air that’s been collected from outside the plane and compressed to the pressure found at sea level? Does this air require warming or cooling to keep the inside of the plane comfortable? b. What is the maximum relative humidity of air compressed to sea level pressure? Does this sound comfortable? c. Compute the temperature and relative humidity again, now assuming that plane is flying through a cloud containing condensed liquid water equal to 1% of the equilibrium vapor pressure. Comment on the magnitude of the changes. picture is given data

1.) A hand pump is used to inflate a bicycle tire to a gauge pressure of 70 psi. a) How much work must be done if each stroke of the pump is an adiabatic process and what is the final temperature of the gas? b) We inflate the tire in two steps: (i) an isobaric compression and (ii) an isochoric increase in temperature. Calculate the work done by gas/"us" and/or heat added/removed during the two steps! Is this a viable alternative to the adiabtic compression Explain! Atmospheric pressure is 1 atm, the air temperature is initially 25° C, and the volume of the air in the tire remains constant. Useful values: A bicycle tire is 26 in diameter and has a cross-sectional area of 2 in² [1 in = 2.54 cm]. 1 lb corresponds to a mass of 0.445 kg. c) For Take-Home only Solve the questions in a) and b) in terms of the initial pressure P₁ = P*, the final volume Vf = V* and the pressure ratio K = Pf/P*!

QV: a hydraulic press is used to compact powdered samples. The device is made of two interconnected cylindrical chambers filled with oil if density psubscripto anc closed by two pistons. The small chamber on the right has diameter d and the large chamber on the left has diameter 5d. A lever is attached to the piston pushing down on the fluid in the small cylinder. The horizontal lever is hinged on the left, at distance L from the small piston, and a force of magnitude Fsubscript0 is applied vertically down at distance 2L from the hinge (Fig.5). You may assume that the lever and pistons have negligible mass. a. Determine the magnitude of the force Fin that the small piston exerts on the fluid in the small cylinder. Hint: you may consider that the lever is at rest in the horizontal position. b. Determine the pressure change applied to the fluid by the small piston. c. Determine the magnitude Fout of the force that the fluid applies to the large piston.
