Mass flow rate: Hot fluid: 1.03 kg/s - Cold fluid: 0.91 kg/s Temperatures: - Hot fluid inlet (Tak 80.5 +/- 10% °C - Hot fluid outlet (T2): 64.0 +/- 10% °C - Cold fluid inlet (Tea): 20.0 +/- 10% °C - Cold fluid outlet (T): 41.0 +/- 10% °C Assume c, constant and equal to 4.2 kJ/kg-K. 1. State assumptions (at least 9 unique ones) and include references. 2. What is the log mean temperature difference in "C? 3. What is the heat transfer rate on the cold side in kW? Heat added or lost on cold side? 4. What is the heat transfer rate on the hot side in kW? Heat added or lost on hot side? 5. What is the effectiveness of the heat exchanger for the given conditions? 6. Calculate the propagation of uncertaintv in kW for part 3 (heat transfer rate on the cold side) and part 4 (heat transfer rate on the hot side).

Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D= 5.9 inches. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 7 -1.00000 * How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? (Round the final answer to four decimal places.) The depth of the mill should be 7071.067 inches.
