A client books a caterer for an event and pays a deposit of $1,000. The caterer has already done initial work, such as menu planning and food preparation, which is valued at $400, when the event is canceled due to unforeseen circumstances. Who keeps the deposit, and how much? The caterer and client split the $1,000 deposit equally, with each keeping $500. The client receives a full refund of the $1,000 deposit. The caterer keeps the entire $1,000 deposit, regardless of the value of work done. The caterer keeps $400 of the deposit to cover the value of the work done and returns $600 to the client.

A hot surface of a plate is cooled by attaching a circular fin (called pin fins) to it. The surface of the plate (left end of the pin) is at 0 °C. The typical fin is 4cm (0.04m) long and a cross-sectional area of A=5x10-6 m2 with a perimeter (P) of 0.006m. The fin is made of cooper with thermal conductivity (K) of 400 W/m°C. The temperature of the surrounding air is T\infty =30 °C with heat transfer coefficient on the surface (including the right end) estimated to be 20 W/m2 °C. a) Use TWO ELEMENTS in your model to estimate the temperature distribution along the fin length (15) marks. b) Find the heat flux in element 1 (5 marks). Note: Please seperately write expression for conductivity matrix and force vectors.
