For most gases at standard or near standard conditions, the relationshipamong pressure, density, and temperature is given by the perfect gasequation of state: p = ρRT, where R is the specific gas constant. For airat near standard conditions, R = 287 J/(kg · K) in the International System of Units and R = 1716 ft · lb/(slug · ◦R) in the English Engineering System of Units.  Using the above information, consider the following two cases: a. At a given point on the wing of a Boeing 727, the pressure andtemperature of the air are 1.9 × 104 N/m2 and 203 K, respectively.Calculate the density at this point.b. At a point in the test section of a supersonic wind tunnel, the pressureand density of the air are 1058 lb/ft2 and 1.23 × 10−3 slug/ft3,respectively. Calculate the temperature at this point.

A thin wire ring, 3 cm in diameter, is lifted from a water surfaceat 20 ° C. Neglecting the wire weight, what is the forcerequired to lift the ring? Is this a good way to measure surfacetension? Should the wire be made of any particular material?

A U-shaped tube is open to air on both ends and filled with water (blue) and an unknown liquid as shown, d = 6.0 cm and h = 20 cm. The density of the water is 1.0 x 103 kg/m³, what is the density of the unknown liquid, in 103 kg/m3? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

Under what conditions may one describe atmospheric processes using the incompressible form of the continuity equation?

Figure 0 shows the change in density of a newtonian fluid with temperature, ing/m^3.Falling spere experiments give average times of 0.2s @ 10 c and 0.23s @ 20 cUsing the equation u=K(ps-pf)tWhere K is found to be 1.34Ps=2300 kg/m3Calculate the viscosity of the fluid at 20 c and 10 c

can someone show me the steps to answer this question. sorry about the handwriting

The primary dimensions of the gas constant over the universal gas constant R/Ru are (a) L2/t2·T (b) m·L/N (c) m/t·N·T (d ) m/L3 (e) N/m

f jon The pilot of a crippled jet was able to control his plane by throttling the two engines. The plane has a weight of 17000 lb and a radius of gyration of kg = 4.7ft about the mass center G. Originally the plane is flying straight at a speed of 1200 ft/s. Neglect the effects of 5000 lb as shown, determine: drag and the loss of fuel. If the thrust in each engine is altered to T₁ = 800 lb and T₂ Remark: The counterclockwise sense is the positive sense. 1.25 ft T₂ 1.25 ft T₁ 1:21:02 7
