Question

Chapter 11, Problem 1P

To determine

State the resultant hydrostatic force acting on the submerged surface. Also, define the center of pressure.

Expert Solution & Answer

Explanation of Solution

Resultant hydrostatic force:

The resultant of the pressure forces acting on the surface is called as the resultant hydrostatic force acting on the submerged surface. The resultant hydrostatic force on the submerged surface needs the computation of direction, magnitude, and line of action of the force.

Center of pressure:

Center of pressure is referred to as the point of application of the resultant hydrostatic force. It is also stated as the intersection point between the line of action of the resultant hydrostatic force and the surface. It is caused by the variation of the hydrostatic pressure.

This is an old exam practice question.

As shown in the figure below, moist air at T₁ = 36°C, 1 bar, and 35% relative humidity enters a heat exchanger operating at steady state with a volumetric flow rate of 10 m³/min and is cooled at constant pressure to 22°C. Ignoring kinetic and potential energy effects, determine: (a) the dew point temperature at the inlet, in °C. (b) the mass flow rate of moist air at the exit, in kg/min. (c) the relative humidity at the exit. (d) the rate of heat transfer from the moist air stream, in kW. (AV)1, T1 P₁ = 1 bar 11 = 35% 120 T₂=22°C P2 = 1 bar

Air at T₁-24°C, p₁-1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate of 3 kg/min and mixes with a saturated moist air stream entering at T₂-7°C, p2-1 bar. A single mixed stream exits at T3-17°C, p3-1 bar. Neglect kinetic and potential energy effects Step 1 Your answer is correct. Determine mass flow rate of the moist air entering at state 2, in kg/min. m2 = 2.1 Hint kg/min Using multiple attempts will impact your score. 5% score reduction after attempt 2 Step 2 Determine the relative humidity of the exiting stream. Փ3 = i % Attempts: 1 of 3 used
