For the system acetone(1)/methanol (2), Iny₁ = 0.64x Based on modified Raoult's law y,P = x,y,P Iny2 = 0.66x Make a Bubble T calculation for P = 200 kPa, and x₁ = 0.4 Make 3rd iterations. Repeat to solve the above problem based on modified Raoult's law and the Wilson and NRTL equations. You can use Excel software to resolve this problem.

I got 10^(-8) instead of 10^(-5) can someone tell me what I'm doing wrong or if my answer is correct?

Using the data below, construct a calibration curve. Include the error bars and the equation of the line and the linearity (R2) of the curve.  Calcium concentration (ppm) (X-data) Absorbance (Y-data) Run 1 Absorbance (Y-data) Run 2  Absorbance (Y-data) Run 3 0.3 1109 1069 1155 1.2 1225 1168 1233 2.1 1472 1319 1389 4.2 1497 1523 1472 8.0 1833 1898 1849 16 2066 2012 2051

This is a picture of a 10-mL graduated cylinder. The value for 'x' says 3 mL and the value for 'y' says a value 1 mL higher than 3. Record the value with proper estimation technique.

Please help me A heat exchanger is to be designed to heat raw water by the use of condensed water at 67°C and 0.2 bar, which will flow in the shell side with a mass flow rate of 50,000 kg/hr. The heat will be transferred to 30,000 kg/hr of city water coming from a supply at 17°C (c, = 4184 J/kg K). A single shell and a single tube pass is preferable. A fouling resistance f 0.000176m ^ 2 * K/W is suggested and the surface over design should not be over 35%. A maxi- mum coolant velocity of 1.5 m/s is suggested to prevent erosion. A maxi- mum tube length of 5 m is required because of space limitations. The tube material is carbon steel ( k = mathfrak 6 W/m K). Raw water will flow inside of 3/4-in. straight tubes (19 mm OD with 16 mm ID). Tubes are laid out on a square pitch with a pitch ratio of 1.25. The baffle spacing is approximated by 0.6 of shell diameter and the baffle cut is set to 25%.The permissible maximum pressure drop on the shell side is 5.0 psi. The water outlet tem-…
