Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

A solar collector absorbed 40 W/m2 heat from the atmosphere. This is equal to the convection brought by air for drying purpose. If the temperature of the air is 40°C while the solar collector area's temperature is 80°C and neglecting effect of radiation, find the convective heat transfer coefficient.
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 heat pump used for heating shown is essentially an air conditioner installed backward. It extracts energy from colder air outside and deposits it in a warmer room. Suppose the ratio of the actual energy entering the room to the work done by the device’s motor is 10.0% of the theoretical maximum ratio. Determine the energy entering the room per joule of work done by the motor given that the inside temperature is 20.0°C and the outside temperature is -5.00°C.
