Water is boiled in a 1-l coffee maker with an immersion-type electric heating element at atmospheric pressure. it was observed that ½-l has evaporated in 13 min once boiling starts. a) if the heating element is rated based on power required to evaporate water, determine the rating of the heating element. b) for the same heating element, how long will it take to raise the 1-l temperature from 18 oc to boiling point at the same atmospheric pressure? take liquid water density air = 1000 kg/m3 & specific heat cpwater = 4.18 kj/(kg. ok).

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
