For Questions 3 and 4: A cup of water was heated to a
temperature of 90°. It was placed in a refrigerator that had a
temperature of 11°C. The water cooled to a temperature of
17°C in 30 minutes. Let the following variables represent
the relevant quantities.
L = Temperature of the liquid
S= Temperature of the surroundings
t = Time
B = Initial temperature of the liquid (Temperature at t = 0
k = Cooling constant
3. Using the Equation Solver, find the value of k in the
equation L = (B - S)e -kt + S. Remember to set the
equation equal to zero and then enter it into the Solver.
Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters.
h= initial height of marble off of table
Y= height of table off floor
X= horizontal distance marble goes from edge of table to where it strikes the floor
a) use the table to find information you need to solve for theoretical range and % of error in measured range.
2. There were 42 mangoes in each crate. 12 such crates of mangoes were delivered to a factory. 4 mangoes
were rotten and had to be thrown away. The remaining mangoes were packed into boxes of 10 mangoes
each. Write a numerical expression in MATLAB syntax to represent this situation and then find how many
boxes of mangoes were there?

Using absolute coordinate system, construct a G-code program for drilling hole number 3 only. To remove the metal chips the hole should be done in three equal steps. During the drilling, coolant should be on before spindle starts and stop after spindle stops. The spindle speed set to 1750 RPM.

Solve to determine the concentrations in each tank. Use 'np.linalg.solve' to solve the system of equations you generate. Assume the tanks are at steady-state (i.e. concentration within each tank is not changing with time) and well-mixed (i.e. the concentration flowing out of the tank is equal to the concentration within the tank). Mass can be tracked by multiplying flow rate, Q (L/s) by concentration, c (mg/L) to give mg/s. Hint: for each tank the mass coming in mg/s must equal the mass going out mg/s, set this up like our two reactor example from lecture 6. Note: Volume balances must hold in addition to mass balances. In other words, the Q entering the tank must equal the Q leaving the tank. You can use this principle to find any values for Q that are missing in the figure. 500 mg/s 221c2 21291 Q13c1 2 02392 Q33c3 500 mg/s 33 = 120 13 = 40 212 = 90 23 = 60 21 = 30arrow_forward
