Refer to the diagram and consider that the pressure in each chamber is equal. Determine the direction ofmovement of the piston, is it going to the left or the right? Prove and justify your answer using equations.
Use the worked example above to help you solve this problem. An airplane has wings, each with area 4.15 m2, designed so that air flows over the top of the wing at 246 m/s and underneath the wing at 221 m/s. Find the mass of the airplane such that the lift on the plane will support its weight, assuming the force from the pressure difference across the wings is directed straight upwards.
Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" and the total mass of the craft is 350 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of gravity on the surface of Mars is about 3.8 m/s2.
Can you help me draw a diagram for each number? thank you
1.)The velocity of the water at the entrance and exit of a pipe are 10 m/s and 3 m/s,respectively. The volume of water flowing inside the tube is 18000 m 3 . What isthe kinetic energy of the water measured at the exit of the pipe?
2. If the exit of the pipe in problem 1 is located at the ground level, what is theelevation of the pipe inlet if all the potential energy is converted to the kineticenergy in problem 1?
3. What is the total thermodynamic heat released by heating 2 kg of solid ice at 0 0 C(2093 J/kg-K) to 100 0 C without steam formation?

- An incompressible viscous flow is contained between two parallel plates separated from each other by distance b. as shown in Figure 1. The flow is caused by the movement of the upper plate which has a velocity U, while the bottom plate is fixed. If U =3 m/s and b= 2.2 cm, and there is no pressure gradient in the flow direction. Fig Q1: Flow between two plates. The bottom is fixed and the upper is moving. Work to 4 significant digits. Enter all values using base units or their combinations, i.e. m, m/s, Pa, N. Do not use multiples as e.g. mm, kPa. You can use values with exponents, such as 0.12e3. a) Start with Navier-Stokes equations and determine the velocity at the point x = 5 cm and y= 0.53 cm. b) Calculate the magnitude of the vorticity at the same point. c) Calculate the rate of angular deformation at the same point.arrow_forwardWhy are the three fluids and one gas layered as they are in this jar?

(Example: Claim - the answer, Evidence - the answer, Reasoning - the answer.) Using this table as well as what you observe in the image, identify a reasonable combination of what the A,B,C, and D layers could be composed. In other words, the claim must correspond with your observation and the information provided to you in the question.arrow_forwardFind work of heart per one beat and (b) work of heart per day (24 hours).
