Q1: Ammonia is absorbed in water from a mixture with air using a column operating at atmospheric pressure and 295 K. The resistance to transfer can be regarded as lying entirely within the gas phase. At a point in the column, the partial pressure of the ammonia is 6.6 kN/m The back pressure at the water interface is negligible, and the resistance to transfer may be regarded as lying in a stationary gas film 1 mm thick. If the diffusivity of ammonia in air is 0.236 cm2 /s, what is the transfer rate per unit area at that point in the column?

In the measurement with the thermoeleman circuit, whose voltage-temperature relation is linear and the calibration coefficient is 0.05 mV/ºC, it was understood that the temperature of the reference end is higher than 0ºC after the measurement point temperature is calculated as 80ºC. To resolve this error, this time the measuring tip was immersed in the water-ice mixture and a deviation of 0.15 mV was observed at the millivolt meter. How many ° C is the first value measured as 80 ° C? a. 76.25 b. 77.50 c. 78.00 d. 75.00 e. 77.00

In the two-pipe system, water flows continuously from the inner pipe and air from the outer pipe (steady-state). ˙The pressure change in both pipes is negligible. In addition, heat interaction with the environment, kinetic and potential energy changes are also neglected. In this system shown in Figure 1, the water flowing from the inlet number 1 is in the state of saturated vapor (gas). In this case, calculate the outlet temperature (T2) for the given system, using the ideal gas approximation for air. (Hint: it will be solved iteratively.)
