Chapter 6, Problem 6.30P

With 3% moisture, 2kg of steam has an enthalpy of 6600KJ. It is heated at constant pressure to a final a final condition of 80 degree superheat. Find pressure of the process and the quantity of heat received by the steam

1. One kg of air is heated and compressed in a piston/cylinder system from 400 K, 100 kPa to 1200 K, 500 kPa. Find As (kJ/kg-K) via: (a) Thermofluids (b) Using the following ideal gas equation: Where: Here, T-K and Cp=kJ/kg-k a 0.9703 As = 2 [/dT - Rin (2) 1 Cp = a +bT + cT² + dT³ b 6.790E-5 с 1.658E-7 d -6.786E-11

Find the quanity of heat required to produce 79% dry steam at 8000 kpa from feedwater at 50 degrees celcius ?.

A piston cylinder contains 22kg of air at 20 degC and 300 kPa. It is now heated up in a constant pressure process to 600 K. Find the final volume.

1 kg of steam expands isentropically from 2.5 MPa & 300 Degrees Celsius to .95 MPa. Find the final quality and Wn, Ws.

A 4 m3 cryogenic storage tank contains nitrogen at 110 K, with quality 25%. Saturatedvapor is now slowly withdrawn while some heat transfer takes place to a final state of110 K, x = 0.65. Find the mass withdrawn and the heat transfer.

QUI A piston-cylinder device with a set of stops initially contains 300 g of steam at 1000 Kpa and 400 C. Find the work if the final state IMpa and 250 C, and work if the position of the stops corresponds to 60% of the initial volume and also find the temperature at the final state if P-500Kpa Steam 300 g 1000 Kpy 400°C e

Correct solution will be liked.

Can you solve this problem (full solution) for my thermodynamics subject. Thank you 4. Five kg of water vapor are contained at 150 kPa and 90 percent quality in a suitable enclosure. Calculate the heat which must be added in order to just produce a saturated vapor. What will the pressure be at the end of the heating process?     Ans. 1045.5 kJ, 168 kPa.
