In a variable volume container, 35 kg of water is heated from 75 °C to 250 °C at a constant pressure of 5 bar. a. [4 pts] How much heat was added to the container? b. [8 pts] If the same amount of heat is instead added to 35 kg of water at 75 °C in a rigid container at a constant pressure of 5 bar, what would be the final temperature?
An 900-g iron block is heated to 380 ∘C and placed in an insulated container (of negligible heat capacity) containing 36.0 g of water at 20.0 ∘C. What is the equilibrium temperature of this system? The average specific heat of iron over this temperature range is 560 J/(kg⋅K).
Problem 3: A 9-m container is filled with 300 kg of R-134a at 10°C. What is the specific enthalpy of the R-134a in the container? Problem 4: a piston-cylinder device contains 0.6 kg of steam at 200 Cand 0.5 MPa. Steam is cooled at constant pressure until one-half of the mass condenses. Show the process on a T-v diagram b) a) Find the final temperature c) Determine the volume change Problem 5:10 kg of R-134a at 320 kPa fills a...
14g of water in a 3.5L container is heated to 200 C. Here, water vapor is treated as an ideal gas. 1) Calculate the number of moles corresponding to the 14g of water. 2) What is the pressure inside the container in units of atm?
7. What is the enthalpy of the R-134a in the container shown? [15 900 kg T 10°C 8. A piston-cylinder device contains water at 600°F. If the volume of the system s 2.4264 fts and the mass of the water is 1 lbm, determine the final pressure and volume if the water is then cooled to 200°F at constant pressure. Draw this process on a P-V diagram. [15]
The pressure differential across a 3.0 m x 5.0 m bulkhead is 900 Pa. What is the effective load on the bulkhead in kg?
