To determine

The flow which is likely meant to be turbulent and explain the reason.

Expert Solution & Answer

Explanation of Solution

The flow which have higher Reynolds number is more likely to be turbulent. Disorders in the velocity fluctuations and more disordered motion characterizes the turbulent flow. The ratio of the inertial force to the viscous force in the fluid is called Reynolds number. Expression for the Reynolds number is given by,

Re=V⋅Dv

Here, V is the flow velocity, D is the characteristic length of the geometry, μ is the kinetic viscosity.

According to the above equation, kinematic viscosity is inversely dependent to the Reynolds number for a liquid having constant velocity and diameter. The higher kinematic viscosity of the air shows the lesser Reynolds number. Thus water flow is more likely to be turbulent.

A piston–cylinder device contains 50 kg of water at 250 kPa and 25°C. The cross-sectional area of the piston is 0.1 m2. Heat is now transferred to the water, causing part of it to evaporate and expand. When the volume reaches 0.26 m3, the piston reaches a linear spring whose spring constant is 100 kN/m. More heat is transferred to the water until the piston rises 20 cm more. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the work done during this process. The work done during this process is kJ.

A 4-m × 5-m × 7-m room is heated by the radiator of a steam-heating system. The steam radiator transfers heat at a rate of 10,000 kJ/h, and a 100-W fan is used to distribute the warm air in the room. The rate of heat loss from the room is estimated to be about 5000 kJ/h. If the initial temperature of the room air is 10°C, determine how long it will take for the air temperature to rise to 25°C. Assume constant specific heats at room temperature. The gas constant of air is R = 0.287 kPa·m3/kg·K (Table A-1). Also, cv = 0.718 kJ/kg·K for air at room temperature (Table A-2). Steam enters the radiator system through an inlet outside the room and leaves the system through an outlet on the same side of the room. The fan is labeled as W sub p w. The heat is given off by the whole system consisting of room, radiator and fan at the rate of 5000 kilojoules per hour.
