(b) Using the schematic below, the above equation can be used to illustrate the development of a sea breeze between cold ocean and warm land. The average temperature of the air column over the ocean is \( \bar{T}_{1} \), and over the land is \( \bar{T}_{2}\left(\bar{T}_{2}>\bar{T}_{1}\right) \). Taking the (nearly) horizontal segments of the circuit as lines of constant pressure (with \( p_{0} \) assumed to be parallel to the surface and \( h \) assumed constant), integrate the righthand side term in the equation for the rate of change of \( C \) along the closed circuit (solid black closed line with arrows in the figure). What sign does \( \frac{d C}{d t} \) have?

Question 6. [10pts] Consider the following block diagram and corresponding difference equation of the so-called $\alpha$-filter: [10pts] Write the difference equation of this system. b) [3pts] Find the transfer function $H(z)$ of this filter. c) [3pts] Find the frequency spectrum of this filter, i.e. find the magnitude of $H(e^{j\omega})$. What kind of filter is this? [3pts] Find the output of this filter if the input $x[n] = (0.5)^n u(n)$. Take $\alpha = 0.5$.

1. Use Python to create a random sample of IQ with sample size 50, which follows a normal distribution with mean 100 and standard deviation 20. 2. Find the sample mean and sample variance of the data using Python. 3. Find the 95% confidence interval of the mean of X. 4. From the data you created, can you conclude that the mean of IQ is greater than 98? 5. Now we want to explore the distribution of and sample variance when n=50.

Question 2 (25 marks) A water-wet piece of wood with dimension 15.15 cm x 14.8 cm x 0.75 cm is dried in a tray dryer at an air velocity of 3.7 m/s. The air temperature is 25 °C at a relative humidity of 40%. The largest surface of the wood is exposed to dry air flowing parallel to the surface. a) Determine the wet bulb temperature and humidity of the air at the beginning of the drying process. (2 marks) b) Predict the constant drying rate in kg H$_2$O/hr.m$^2$. (10 marks) An experiment was subsequently conducted to verify the predicted drying rate obtained in Q2(b). The following data were obtained from the drying test: moisture content (dry basis) of the wood as a function of time was obtained and summarized in Table Q2. Assume that the wood dry density is 0.5 g/cm$^3$. Table Q2 Time, h Free moisture content, X (kgH$_2$O/kg dry solid) 0 1.26 2 0.968 3 0.835 4 0.736 7 0.517 9 0.418 12 0.308 16 0.209 18 0.165 c) Find the constant drying rate from the experimental data in Table Q2 using graphical method. (7 marks) d) In your own words, comment and discuss on the values obtained from the predicted drying rate (part (b)) against the experimentally determined drying rate (part (c)) (5 marks) e) Determine the critical moisture content (1 mark)
