During a high reynolds number experiment, the total drag force acting on a spherical body of diameter d = 12 cm subjected to airflow at 1 atm and 5°c is measured to be 5.9 n. the pressure drag acting on the body is calculated by integrating the pressure distribution (measured by the use of pressure sensors throughout the surface) to be 4.9 n. determine the friction drag coefficient of the sphere. take the density and kinematic viscosity of air at 1 atm and 5°c as rho = 1.269 kg/m3 and v = 1.382 × 10–5 m2/s and the drag coefficient of the sphere in turbulent flow as cd = 0.2. (round the final answer to four decimal places.)

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference

Precipitation hardening can be achieved in many light alloys by a three-step heat treatment. what is carried out and what is the purpose at each step? why is such a treatment necessary based on the nucleation and growth theory of phase transformation. compare this treatment with tempering martensite for carbon steels (similarities and differences).
