Match the equation with the graph. Include the directrix that corresponds to the focus at the origin. Label the vertices with appropriate polar coordinates. If the equation is an ellipse, label the center as well.\\ $r = \frac{5}{1 + \cos \theta}$\ Choose the correct graph below.\\ Graphs are [-10, 10, -10, 10] with Xscl = 2 and Yscl = 2.\ Find the polar coordinates of significant points on the graph. Select the correct choice below and fill in the answer boxes to complete your choice.\ (Type ordered pairs. Type exact answers, using $\pi$ as needed. Use angle measures greater than or equal to 0 and less than $2\pi$. Use a comma to separate answers as needed.)\ A. The graph is an ellipse.

Assessment 3 - EHHMT2A.pdf The Unit Operations Laboratory consists of a Continuous Distillation pilot-plant (Figure 1). The plant is mainly composed of a mash-packing column, pre-heater with electrical resistor, a condenser, feed pump and a double-pipe heat exchanger. The pre-heater is used to heat up the raw material that is fed into the column on a continuous basis. The pre-heating system has not been used since the beginning of lockdown (March 2020). This often has detrimental effects on the performance of the pre-heater. You are required to perform a pre-liminary design study to investigate the extent of loss on the performance. The resister is operated to release 38.3% of its maximum capacity (W) and is used to heat the water to a state of saturated steam a vapour pressure of 2500 dyn/cm². Figure 1. P&ID diagram for a Continuous Distillation pilot-plant. a) Determine the surface (wall) temperature (°C) of the heating resistor using Fig. 2 $\left[Hint: A = \frac{d_h}{2}\right]$ [16] b) Estimate the boiling heat transfer coefficient, in W/m². K and determine the percentage reduction if the initial coefficient was 63 000 W/m². K. [6] c) Assuming the air conditioning system at the lab is switched on and the room temperature is maintained at 53.6°F and the thickness of the pre-heater (glass window) is 2 cm. Estimate the heat lost (kW/m²) to the surroundings if the convective coefficient of air is 9852 W/m². K. [10] d) Calculate the amount of heat absorbed (W/m²) by the water in the pre-heater. [3]
