Please solve the calculation part all and in detail

Laboratory Title Tray Dryer Course Title Unit Operations-1 Results \& Calculations: Mass of empty tray =1.038kg 4.6: Calculations: Write the formula for moisture content and calculate the moisture content and tabulate the data Mass of dry solid = mass of final product - mass of equilibrium-moisture : * assume that the equilibrium-moisture content is 0.05g water/g dry solid \% Moisture content at time t=[ [mass of solid at time t - mass of dry solid)/mass of dry solid] Rate of drying = (moisture content at time t2 moisture content at time t1)(t2t1)min Given: Mass of final product =. Mass of equilibrium-moisture =0.05g (Based on Assumption) 4.5 Data: Tray size 3040cm Weight of dry sand =4.798.kg Air velocity =.0.5m/s Wet bulb temperature .24.81..C
