b. An electric heater supplies (R+ 2.5) kW of power in the form of heat to water. If in 5.5 hours, 350 kg of water is heated from –10°C to 60 °C, find the work done (w) of heater. Also calculate the amount of heat energy (Q) transferred to the water. Consider the specific heat of water is 4184 J/kg K. R=30
This question deals with a cylinder, which is upright. Here are the facts for the problem. Can you please help me with a clear diagram and then the right equations for net work and heat? There is a massless and frictionless piston inside the cylinder with two stops which prevent movement down the cylinder. But, the cylinder can still move upward. Under the Below the piston is 5 kg of water, 50% of which (by mass) is initially vapor at 120°C. Heat is gradually added to the water until the water reaches a final state of 400°C. The atmospheric pressure is 500 kPa. The stops don't affect the area. (1) Draw a P-V diagram for the process, which includes the isotherms at states 1 and 2. (2) A what temperature does the piston first lift off? At what temperature has the liquid turned to vapor? (3) What is the net work and heat transfer between the system and the surrondings between states 1 and 2. Are these transfers going into or out of the system?
A cylinder of gas has a frictionless but tightly sealed piston. 1250 J of heat is added to the gas. If the change in the internal energy of the gas is -520 J. How much work is done by the gas? O zero -730 J -1770 J O +1770 J O +730 J
A windmill produces 5 kW and is connected to a battery to charge it. The batterydue to resistive heating loses heat at a constant rate of 2 kW. Find the stored energyin the battery after 2 hours?
1 - Consider 2 kg of water in a cylinder blocked by a piston at 20 C, 200 kPa. Water is heated and piston starts to rise. When the piston reaches the blocks, the volume of water has doubled. Heating continues until the pressure also doubles. Calculate the work done by water and the amount of heattransfer. Consider the case that the piston is restricted by the linear spring. Initially the spring is at rest. Water is heated until the piston reaches the blocks. Just before it hits the blocks the pressure is twice the initial pressure. Calculate the work done by water and the amount of heat transfer by the time the piston reaches the blocks. 7 D H₂0
