Water flow with a density of 998 kg / m3 at 70 ° C enters the system at a speed of 0.5 m / s and a 20 cm diameter pipe is pumped to a 2.5 m high reservoir with the help of a 7.5 kW pump. With the heater at the exit of the system, 1300 kW of energy is transferred to the water flow. Calculate the exit temperature of the water. (With reference to the height Z1, Z2 = 2.5 m is acceptable, ignore kinetic energy changes.) heater Pa pump and turbine P1 Ws reference plane O--
The beating of the human heart can be modeled by a thermodynamic cycle. In this chapter, we have used PV diagrams to show processes occurring for a gas. Such diagrams can also be used for a liquid, such as blood in the heart. The figure below shows an idealized cycle for the left ventricle (LV) during a single beat of the heart. P(mm Hg) 120 78.0 20.0 10.0 A V (mL) 44.0 149 The cycle begins at point A with the opening of the mitral valve, which fills the LV with blood from the left atrium. During this process, the pressure and volume of the blood in the ventricle increase linearly until the mitral valve closes at point B. At that point, the muscles surrounding the LV contract, increasing the pressure of the blood. Because both the mitral and the aortic valves are closed, and because blood is essentially incompressible, the process is isovolumetric. The pressure increases to the diastolic pressure of 78.0 mm Hg (1 mm Hg = 133.322 Pa) at point C. Now, the aortic valve opens, pumping the…
One mole of a gas obeys the Ideal Gas Law PV = 20T, where P is pressure, V is volume, and T is temperature. If the temperature T of the gas is increasing at the rate of 5 °C/s and if, when the temperature is 80 °C, the pressure P is 10N/m? and is decreasing at the rate of 2- find the m2 . s rate of change of the volume V with respect to time.

1.1 Find the rate at which water will flow in each pipe, ignoring the shock losses at P and entry to pipelines A and B. 1.2 Find the pressure at P. QUESTION 2 The diameter of an open-topped tank 1.5 m high increases uniformly from 4.2 m at the [2 base to 6 m at the top. Discharge from the base of the tank takes place through a 75mm diameter pipe which is 3 m in length. The pipe discharges the water to the atmosphere 1.5 m below the base of the tank. Initially, the tank is fully filled with water. Take f = 0.01. Find the time to empty the tank. QUESTION 3 Water must flow over a distance of 2 800 m from a large catchment dam to a turbine. [10 The water level in the catchment dam is 1 620 m above sea level and the turbine is situated 1 275 m above sea level. The efficiency of transmission is 65% and 300 kW must be transmitted from the pipeline to the turbine.
