A small-scale Compressed Air Energy Storage (CAES) system uses a rigid tank, whichhas been sized to 1m3. The air storage helps support various fluid power (pneumatics)requirements, but also serves for energy storage (when fully charged).The tank sits in a plant room having a temperature of 25oC at 1 atmosphere (101.325kPa).When delivered new and installed the tank (and the ambient air it contains) is assumedinitially at the same steady state conditions in the plant room. The tank can be filled with(dry) air to a maximum pressure of 300bar. When left in the plant room, the pressurised airtank eventually attains the plant room temperature.You may assume:> Steady state conditions apply> Negligible changes in kinetic and potential energy> Thermal mass of the tank (metal) is negligible Apply the ideal gas equation and calculate the mass of 25oC air (units: kg) in the fullypressurised tank.
You are designing an electric air heater for large conference rooms. A 75mm OD, 4mm wall thickness intake pipe sucks air into the unit at 2 m/s. The air passes over a 3m long heater coil and is exhausted at a temperature of 38degC. What is the average heat rate of the heater coil into the air?

n electric generator at a power plant produces energy by passing superheated steam from a high temperature container (reservoir), through a pipe connected to a series of fans, and then into a low temperature reservoir. As the steam passes across the blades of the fans some of the heat energy of the steam is transformed into mechanical energy, which turns the fans which in turn are connected to a generator, which in turn converts the mechanical energy into electrical energy. If the high temperature steam has a temperature of 412.1 K and the low temperature reservoir has a temperature of 105.4 K, what is the Carnot efficiency of this process?
A power station uses oil-fired boilers which are supplied with fuel from 4 cylindrical tanks, each with 12 m diameter and 11 m high. The calorific value of the oil is 38,039 kJ/kg and its relative density is 0.78. The output from the power station is 77 MW. Assuming the only 21% of the heat input is converted to into electrical energy output, how long will the boilers run (in days) on the oil in the tanks. Correct Answer: 4.7 ± 0.1
A reservoir of 20oC water is pushed at a rate of 5 kg/s to a 3 in Sch. The 40pipe is linked to a relatively big storage tank. The tank is 7 meters away from the reservoir, and the pump, which produces 30 kW of power, is positioned on its side. Heat is absorbed by the fluid at a rate of 3.5 kW. Calculate the temperature of the receiver tank.
You, a process design engineer, are tasked to build a powerplant that utilizes 1.5 metric tons of municipal solid wastes (MSW) per hour. In an industrial boiler, MSW is burned to heat and pressurize 1 kg/s of preheated water to high-pressure steam (44 atm, 450 °C). The high-pressure steam, moving at a linear velocity of 70 m/s, is then used to drive a high-pressure turbine. In a heat exchanger, the used steam from the outlet of high-P turbine at an intermediate pressure (10 atm, 250 °C) is used to preheat the water that will be fed to the boiler. This water is pumped from an underground reservoir at a low velocity (1 atm, 25 °C). After preheating the water, the intermediate-pressure steam leaving the heat exchanger is then used to drive a low-pressure turbine. Lastly, the steam from outlet of the low-P turbine leaves at a velocity of 10 m/s (at 1 atm and 100 °C) via an exhaust 10 m above the pump inlet. The industrial boiler is insulated, but due to the high temperatures and the nature…
Q3 a) A rectangular duct with width of 0.3 m and height of 0.2 m is used to deliver cold fresh air to a medium size master bedroom. Heat from roof causes the internal surface temperature of the duct to be 40°C. The fresh cold air enters the duct at 17°C and exits at 23°C. Given the volumetric flow rate of the fresh cold air which enters the duct is 0.15 m/s, assuming the flow inside the duct is fully developed: i) State two assumptions for analyzing this problem ii) Calculate the Reynolds number for the flow inside the duct iii) Calculate the heat transfer rate to the fresh cold air inside the duct, kW iv) What is the minimum length of the duct to keep the exit temperature at 23°C, m b) Will the exit temperature remain the same which is at 23°C, if the length of the duct is increased 5 times of the length calculated in iv)?
