WebHelium expands polytropically steadily through a turbine according to the process pV1.5=C. The inlet temperature is 1000°K, inlet pressure 1000 kPa, and the exit pressure is 150 kPa. The turbine produces 100,000 kW. Determine (a) the exit temperature; (b) the mass flow rate kg/sec. RHe= 2.077 kJ/kg.K; k=1.666. Draw and label the P-V and T-S ... WebApr 7, 2024 · According to the definition of specific gravity, it can be mathematically expressed as : S G = ρ s u b s t a n c e ρ w a t e r. In general, the specific gravity of any substance is defined relative to water at 4⁰C. This temperature is considered because the water density at that temperature is 1000kg/m³ or 1g/cm³.

WebThe specific gravity of some common gases can be found in the table below: As a reference, normal air has a specific gravity of 1. If the specific gravity is greater than 1 the gas is heavier than air and the vapor will be found low; the larger the number the heavier the gas is and the lower vapors will be found.
