Water at 10°C flows through the system shown in the figure below at 0.34 m/s. Energy loss in the 40-cm pipe is negligible. Energy loss in the 30-cm pipe is known to be 1.5V2. A mercury manometer indicates that the absolute pressure at the top of the 30-cm pipe is 749.5 mm Hg abs. The pressure of the surroundings is 101,330 Pa. Calculate the power input to the pump. p = 749.5 mm Hg Clouotion

Completely solve and box the final answer. Write legibly. Water flows at the rate of 65 kg/min through a double pipe counter flow HX. water is heated from 50deg C to 75deg C by an oil flowing through the tube. the specific oil is 1.78 kJ/kg-K. the oil enters at 115 deg C and leaves at 70deg C. the overall heat transfer coefficient is 400 W/m2-K. Calculate the rate of heat transfer and the required number of tubes with OD = 30mm and L = 4m.

A thermometer reading 10°C is brought into a room with a constant temperature of 33°C. If the thermometer reads 15°C after 3 minutes, what will it read after being in the room for 5 minutes? For 10 minutes? C After 5 minutes, the thermometer will read °C. (Do not round until the final answer. Then round to the nearest hundredth as needed.)

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5.  1 pass 2 fail 3 fail 4 pass

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

Please show system sketches and related energy flows for all problems. Solve the following: The utility providing the electricity to the boiler in problem 1.1 uses the same fuel as that used in problem 1.4 and has an efficiency of 0.35. The cost of the electric boiler is, $3,000 with a 15 year lifetime. The cost of the fuel based boiler system is $5000 and has a lifetime of 20 years. The fuel cost is $0.10/kg and the cost of electricity is $0.20/kWh. There is a tax charge of $0.50/kg of CO2 emission that is passed on to the user whether the utility based electrical system or gas fired system is used. The unit is used for 10 hours per day, 280 days per year. Which process would you recommend in terms of fuel consumption, exergy production, carbon dioxide emission and theroeconomic cost? There is no cost associated with the water input. Note the total amount of fuel consumed is directly related to the carbon dioxide emission from each process.   Show below are the problems described in…
