Please answer the following question

State true or false 1. The critical radius of insulation for a cylinder is given by h 2. In transient heat conduction, the two significant dimensionless numbers are Biot number and Fourier number. 3. As the thickness of the plane wall increases, the rate of heat transfer decreases. 4. In two concentric black cylinders, if 1 represents the outer surface of the inner cylinder of diameter d, and 2 represents the inner surface of the outer cylinder of diameter d2, then d, F22 is given by d2 5. The temperature distribution along a fin with insulated tip is given by e - mx

QUESTION 2 ' а) Besides temperature measurement that is based on thermal expansion, there are also thermal sensors that are based on other factors. i. Describe on how the RTD and thermistor measure the temperature and difference between them. ii. Given the temperature for RTD in Figure 1 is 155°C, coefficient of resistance for RTD, a is 0.0035°C'' and resistance for the RTD is 352 at 0°C. The bridge is operated in a balanced condition. Find the value of R1, if R2= R3. R3 R2 G RTD RRTD Ri E, Figure 1 Wheatstone Bridge

3. Microfluidic channels will need to be fabricated on a key micro-scale sensor used by aerospace industries. Before running machining tests and analyzing machined quality, preliminary efforts are needed to evaluate selected materials and factors affecting machining process¹. Three material candidates have been selected, including 422SS (stainless steel), IN718 (nickel alloy), and Ti64 (titanium alloy) with their measured tensile properties and equation of true stress-true strain relationship used listed below. Tref25°C. Specifically, three factors will need to be evaluated, including different materials, temperature, and size effect. Please calculate true stress values for true strain ranging between 0-3 for each case listed below. Material A (MPa) & (S-¹) Tm (°C) 870 0.01 1520 422SS (Peyre et al., 2007) IN718 (Kobayashi et al., 2008) Ti64 (Umbrello, 2008) 980 1 1300 782.7 1E-5 1660 Material 422SS (CINDAS, 2011) IN718 (Davis, 1997) Ti64 (Fukuhara and Sanpei, 1993) 0 = X G (GPa) 1+ B…
