A steel cylindrical air receiver with 5 ft. diameter and pressure load of 180 psi, design stress of 9500 psi maximum. The pressure vessel is to be provided with 1 ½ in. diameter drain valve installed at the bottom of the vessel and safety pressure relief valve installed either at the top most or at the side with pop – out rating of 200 psi. Assume a 100% weld joint efficiency. The lap welding tensile strength is 65,000 psi. Determine the bursting pressure of this air receiver.

 

A sump pump is draining a flooded basement at the rate of 0.750 L/sec with an output pressure of . The water enters a hose with 3 cm inside diameter and rises 2.50 m above the pump. What is the pressure at this point?

Which material is best for Pressure Vessel?

A regenerative gas turbine power plant is
shown in Fig. P1. Air enters the compressor at 1
bar, 27ºC with a mass flow rate of 0.562 kg/s and
is compressed to 4 bar. The isentropic efficiency of
the compressor is 80%, and the regenerator
effectiveness is 90%. All the power developed by
the high-pressure turbine is used to run the
compressor. The low-pressure turbine provides the
net power output. Each turbine has an isentropic
efficiency of 87% and the temperature at the inlet
to the high-pressure turbine is 1200 K. Sketch the
corresponding T – s diagram and determine: (a) The net power output, in kW. (b) The thermal
efficiency. (c) The temperature of the air at states
2, 3, 5, 6, and 7, in K.
