Q3. The data listed in the following table gives hourly measurements of heat flux q (cal/cm? /h) at the surface of a solar collector. As an architectural engineer, you must estimate the total heat absorbed by a 150,000-cm2 collector panel during a 14-h period. The panel has an absorption efficiency eab of 45%. The total heat absorbed is given by: h = eab q A where A = area and g = heat flux. 4 6. 10 12 14 0.10 5.32 7.80 8.00 8.03 6.27 3.54 0.20
A water tube boiler has a capacity of 1000 kg/hr of steam. The factor of evaporation is 1.3, boiler rating is 200%, boiler efficiency is 5%, heating surface area is 0.91 m²/boiler Hp, and the heating value of fuel is 18,400 Kcal/kg. The total coal available in the bunker is 50,000 kg. Determine total number of hours to consume the available fuel. 1.
Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change.(i) Calculate the steam mass flow rate.

Completely solve and box the final answer. Write legibly Determine the mass flow rate of steam through a nozzle having isentropic flow through it. Steam enters the nozzle at 10 bar, 500°C, and leaves at 6 bar. The cross-section area at the exit of the nozzle is 20 cm2. The velocity of steam entering the nozzle may be considered negligible. [Ans. 2.2 kg/s] Note: Please don't copy the answer/solution from the internet, I need a more in-depth solution for this problem. Thank you

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.
