1. A steam iron consists on both heating plate and steam diffusing system that releasing hot steam while ironing clothes. Below are some technical specification of a steam iron (brand X), presented in Table 1. The steam iron consists two heating elements: one is for the heating plate, and other is for heating up steam in the water chamber, shown here in the diagram X. It can operate on either heating plate or steam diffusing system or in both systems simultaneouly Table 1. Specification of steam iron Specification Details specification Water tank capacity 1800 ml Continuous steam rate Max 120 g/min Power Max 2100 W Voltage 240 V Figure 1. Steam iron which works as hot plate and steam diffuser e. Supposed that you are planning to upgrade the old steam iron system to a new improved model which is able to increase ironing capacity with minimum change in power usage as per details in Table 2. Table 2. Difference between the old and new steam iron model New, improved model 20 clothes/hrs Old model Number of ironed 5 clothes/hrs clothes Period of operations Maximum 2 hours Power usage (W) Maximum 5 hours Expected to increase up to 10% power usage i. List three (3) different approaches in solving this problem and analyze the applicability of each approach. You may consider both design and operational changes in achieiving the target, however your analysis must take into account the thermodynamic point-of-view
