3. Consider the following equation. All three of the terms in parentheses are dimensionless groups. Because kc is difficult to determine directly, the other variables are measured and kc is calculated from the given equation. 26 THERMODYNAMICS 1 MODULE 1 FUNDAMENTAL CONCEPTS ]3 [ _d>vp_jo8 p DAB kc D = 0.023 [H DAB What is the estimated value of kc? What are the units of kc? Show your work. The following values were measured: D = 8.0 mm, DAB = 0.475 cm²/s, µ = 1.12 x 103 N-s/m², p = 1.00 x 10-³ g/cm³, v = 15.0 m/s.

Q1 please

The equation of state of an ideal gas describes the relationship between its pressure p, volume V, and temperature T as: PV = nRT where n is the amount of substance of gas (number of moles), and R is the ideal gas constant. What are the dimensions of R?

A Pitot tube measures a pressure difference Pa = Pt- Ps (dynamic = total - static) between the front and side of the Pitot tube. The dynamic pressure is given by the kinetic energy due to the airspeed v, allowing airspeed to be calculated from the measured pressure difference. (a) P₁ = ² pv² ⇒ v= When designing a Pitot tube, a manufacturer wants to make it precise enough to measure airspeed to within 0.5 % uncertainty, i.e. = 0.005, at sea level. Av p=(1.225 +0.0005) kg/m³ at sea level. (b) 2Pd Av Using error propagation, derive an expression for Simplify as much as possible! ΔΡΑ Pd Calculate the maximum permissible %-uncertainty in Pa, i.e. allow the Pitot tube to meet the manufacturer's requirements. Hint: Answer 1% x 100, that will

Fill in the chart.  The total mass is 505g.

We wish to measure a characteristic of a machined part whose nominal size is 50 mm at 20 °C. For this, two different instruments are used; an analog micrometer and a digital vernier caliper, both recently calibrated and with the same resolution (0.01 mm). The calibration certificate data of the analog micrometer and the digital vernier are shown in tables 5 and 6 respectively. In both cases the calibration uncertainty does not include the contribution of resolution uncertainty. Additionally, there are drift studies for both instruments and it is established that the drift of the micrometer is ± 0.002 mm while the drift of the vernier is ± 0.02 mm.   The same number of measurements were performed with both instruments to avoid repeatability biases under controlled environmental conditions. Table 7 shows the results of the measurements of both instruments. The temperature of the piece was monitored with a digital thermometer whose calibration uncertainty is 0.1 °C, which already includes…

I am confused about how this expressions was simplified. Can someone walk through this step-by-step?
