Dry-bulb temperature of the air as it exits the heating coil : In a heating/humidifying system moist air first flows through a heating coil and then through an air washer. The air enters the system at 55 °F dry-bulb temperature and 40 % relative humidity. The air exits the system at 90 °F dry-bulb temperature an..

Determine the final temperature for this adiabatic process : An insulated piston cylinder device contains the R-134a at 600 KPa with quality 95%, the volume at this state is 0.3 m^3. The piston then expands until it is a saturated vapor. During that process, 100 KJ of work is done. Determine the final temperat..

What is the final total enthalpy of the water : A liquid/vapor water mixture with 2.7 lbm and a pressure of 1000 psia is heated at constant pressure until the temp is 600ºF. What is the final total enthalpy of the water, in BTUs?

What is the local heat flux : Laboratory measurements of water flowing across a flat plate indicate a local shear stress of 2.3 Pa. the free-stream velocity of the water is 5 m/s. If the free-stream & plate temperature are 15 C & 60 C, respectively, what is the local heat flux?

What is the local heat transfer coefficient : A flat plate maintained at a temperature of 50 C experiences a flow of atmospheric air at 15 C. If the temperature gradient at the plate's surface at a given downstream location is -43 C/mm, what is the local heat transfer coefficient?

Water flows across flat plate at a velocity : Water at 20 C flows across a flat plate at a velocity of 0.25 m/s. compute the distance from the plate’s leading edge to where the laminar boundary layer thickness is 3 cm. Verfiy that the flow is indeed lamiar at this distance.

Water in thermal equilibrium-trailing edge of the plate : Water in thermal equilibrium with a 50 C plate flows across the plate at a velocity of 0.5 m/s. find the length of the plate required such that the critical Reynolds number is achieved at the trailing edge of the plate.

Determines work done and heat transfer : For the cylinder-piston shown, piston is initially resting on the lower stops. The cylinder contains 1 kg of water at 1 bar and x = 0.64. A pressure of 3 bars is required to move the piston. The system is now heated until the water reaches 600° C.

Water undergoes a cycle composed : A system consisting of 1 kg of water undergoes a cycle composed of the following processes: constant-volume heating from p1 = 500 kPa, T1 = 160°C to p2 = 1000 kPa. constant-pressure process to saturated vapor.
