Hi tutor, please answer in 30 minutes with explanation.
On a 5 day wilderness expedition you'll need to heat 3.0kg of water to the boiling point each day. The air temperature will average 25°C. You have available canisters of compressed propane C3H8 fuel, which you'll burn to heat the water. Each canister has 100.g of propane in it. What is the minimum number of fuel canisters you must bring? The standard heat of formation of propane at 25°C is −103.85/kJmol.
Solve first question only.
Two canisters A and B each contain 0.20 mol of a diatomic gas at 400 K and a pressure of 405300 Pa. A expands isothermally and B adiabatically until the pressure of each is 303975 Pa. [Hint: for a diatomic gas Cv = = (5/2) R.] (1) Sketch both processes on a single PV-diagram. (2) What are the final temperature and final volume of each canister.
A feed of 4535 kg/h of a 2% salt solution at 311 k enters continuously a single effect evaporator and is being concentrated to 3%. The evaporation is at atmospheric pressure and the area of the evaporator is 69.7 m2. Saturated steam at 383.2 K is supplied for heating. Since the solution is dilute, it can be assumed to have the same boiling point as water. The heat capacity of the feed can be taken as Cp = 4.10 Kj/kg – K. Calculate the over – all heat transfer coefficient.
Completely solve and box the final answers. Use 3 decimals at all instances. WRITE LEGIBLY OR TYPEWRITE THE SOLUTIONS.
