Bài 1: Một bình chứa khí nén có thể tích 6 m3 nén ở áp suất 8 bar, nhiệt độ 296K.
- Hãy xác định thể tích khí ban đầu khi chưa bị nén là bao nhiêu?
- Nếu làm lạnh khối khí ban đầu khi chưa bị nén ở nhiệt độ 100c thì cần bình chứa có dung tích là bao nhiêu?

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.
