Discharge of ethylamine (C2H5NH2) from a fuel storage vessel 3.0m high via a broken 25mm nozzle on tank base. Storage temperature is 65°C, vapour pressure is 5 bar (or 5 x 105 Pa). Liquid density is 680 kg/m3. Atmospheric pressure is 1 x 105 Pa. What is the Mass flow of the discharged liquid? Between 10-12 Kg/sec Between 5-8 Kg/sec Between 8-10 Kg/sec

Liquid food is flowed through an uninsulated pipe at 90 ° C. The product flow rate is 0.35 kg / s and has a specific mass of 1000 kg / m³, specific specific 4 kJ / (kg K), viscosity 8 x 10-6 Pa s, and a thermal conductivity of 0.55 W / (m) K). The assumed viscosity change is negligible. The internal diameter of the pipe is 25 mm with a thickness of 3 mm made of stainless steel (k = 15 W / [m ° C]). The outside temperature is 15 ° C. If the external convective heat coefficient is 18 W / (m² K), calculate the heat loss at steady conditions per meter of pipe length. A. Find the convection coefficient in the pipe = W / m² ° C. b. Calculate Heat loss per meter pipe length = watt

Steam flows in a Schedule 40, 6" (NPS) nominal pipe size 1000 ft long pipe, with roughness 45 micron. The steam enters the pipe at 200 oC. The steam flow rate is 45,000 lb/hr and the pressure at the entrance of the pipe is 10 bar. The pipe is well insulated and the flow of steam is considered isothermal. Assume that the steam behaves as an ideal gas with constant viscosity 0.018 cp. The molecular weight of steam is Mw=18 kg/kmol. Calculate the pressure of the steam at the outlet of the pipe (in bar)
