d) The following figure is a diagram of a domestic hot water system. The gas valve is operated by the controller, which in turn, is operated by the temperature measuring and comparing device. The gas valve operates the main burner in full-on/full-off modes. The check valve in the water inlet prevents reverse flow due to overpressure in the hot-water system, and the relief valve opens when system pressure exceeds 100 psi. Control of the temperature is achieved by the controller...

spring relief disk 3. (40 pt.) A pressure cooker cooks a lot faster than an ordinary pan by maintaining a higher pressure and temperature inside. The lid of a pressure cooker is well sealed, and steam can escape only through an opening in the middle of the lid. The pressure relief valve consists of a spring-loaded disk that is positioned over this opening. Consider that a certain portion of a pressure cooker is initially filled with water and put on...

DATA FOR THE QUESTION IS :
Question #1 10 marks Draw a simple hydraulic Circuit which will operate a hydraulic cylinder of a machine. The load during forward stroke is 15 KN and that during return stroke is approximately 9.5 KN. The forward and return speeds are about 3.5 m/min and 5.5 m/min respectively. The total stroke of the cylinder is 400 mm. A provision is required to hold the cylinder anywhere in between the end positions. Select the different...
