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.
Latent heat of fusion is the heat given up as a substance freezes. The latentheat of fusion for water is 144 British thermal units per pound (Btu/lb). Thismeans that 144 Btu are given up for each pound of water that freezes. Howmany British thermal units of heat are given up when 4,000 pounds of waterfreeze?
Q1: If a calorimeter is not assumed to be adiabatic, how would one calculate the heat transfer? Guide Questions: What are the parameters to be considered and the equations to be used? What law of thermodynamics does this transfer of heat to the surroundings touch? Is an adiabatic system automatically considered as a closed system? Please help me understand by also attaching a reference/book/journal article. This would help me in my essay. Thank you.
Half a liter of liquid is being heated in a closed container to prepare food. Initial temp is 25C and desired temperature is 85C. How much energy is needed to raise the temperature of this amount of water as described? Specific heat of water is given as 4.18 kJ/(kg.K)
Pls.answer thank you! A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.

A liquid reactant solution is pumped through a pre-heater before entering a reaction vessel. The solution enters the pre-heater at 25 °C and must enter the reactor at 45 °C. The flow of the reactant solution is 1500 mL per minute. The density of the reactant solution is 0.91 g-cm3 and the heat capacity is 1.75 Jg1.K1. ASsume there is no heat loss in the pre-heater or between the pre-heater and the reactor. a. Draw a schematic of the pre-heater, detailing all mass and energy flows. b. Clearly define a system boundary. c. Write the general energy balance, and a simplified energy balance stating all assumptions that apply to this problem. d. What is the minimum power rating required for the pre-heater?
The brewing process involves 4 steps. Boiling, Fermenting, Filtering and Kegging. The batch size is 100 gallons for the boil and fermentation tanks. Process times for the different steps are Boiling: 8 hours/100 gal, Fermenting: 15 days/100 gal, Filtering: 10 gal/hour, Kegging 10 min/5 gal. In order to improve the productivity they decide to introduce a holding tank between the fermentation and filtration steps. They are able to drain the fermentation tank at a rate of 30 gal/hour. Ferment WIP Keg Boil Filter What is the minimum WIP tank size they need? (Round your answer to the nearest 10 gallons) Assume 24 hours/day
Hi guys, Data assumption coal boiler operation : Steam consumption = 300 kg steam/shift, coal price per kg = $0.5, coal calorie = 6300 Kcal/kg. Questions: 1. how to calculate cost ($) steam per shift ? 2. how to calculate steam calorie per shift ? Thanks
H.W1: Warm air is contained in a piston-cylinder assembly oriented horizontally as shown in Figure below. The air cools slowly from an initial volume of 0.003 m³ to a final volume of 0.002 m². During the process, the spring exerts a force that varies linearly from an initial value of 900 N to a final value of zero. The atmospheric pressure is 100 kPa, and the area of the piston face is 0.018 m². Friction between the piston and the cylinder wall can be neglected. For the air, determine the initial and final pressures, in kPa, and the work, in kJ. A = 0.018 m² Patm = 100 kPa Air Spring force varies linearly from 900 N when V = 0.003 m³ to zero when V, = 0.002 m³
