A batch blending process consists of a blending tank that mixes five liquid ingredients. The ingredients are designated as A, B, C, D, and E. Each ingredient is controlled by an ON/OFF solenoid valve. The following statement list could be used to control this process: Initial Condition: Drain valve OPEN, ready light ON, all liquid valves OFF, mixer OFF. STEP 1: (1 to 3 s) Press START switch STEP 2: (20 s) Drain valve CLOSED, ready light OFF, valve A...

The kinetics of a reaction A + B + C → D are being studied. By comparison with the first experiment it is found that i) Keeping [B]0 and [C]0 constant and increasing [A]0 by a factor of 4 causes the reaction to go eight times faster initially. ii) Keeping [A]0 and [C]0 constant and decreasing [B]0 by a factor of 2 causes the initial rate to increase by a factor of 1.414. iii) Doubling the initial concentrations of A,...

Three different washing solutions are being compared to study
their effectiveness in retarding bacteria growth in five-gallon
milk containers. The analysis is done in a laboratory, and only
three trials can be run on any day. Because days could represent a
potential source of variability, the experimenter decides to use a
model that reduces experimental error (and hence increases
precision) by grouping days into blocks. Observations are taken for
four days, values in table below show measurement of effectiveness
