The flow rate of water in a 12-cm-diameter pipe is measured with a 6-cm-diameter venturi meter to be 0.09 m3 /s. What is the expected deflection on a water-mercury manometer? Assume a water temperature of 20°C.
the load on a 2 inch diameter hydraulic cylinder increases from 10000lb to 15000lb. due to compressibility of oil the
A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350oC and velocity of 15 m/s. The exit is at 100 kPa, x = 1 and very low velocity. Find the specific work and the power produced.
air at t11300 0r p116 lbfin2 enters a counterflow heat exchanger operating at steady state and exits at p214.7 lbfin2.
a system consists of liquid water in equilibrium with a gaseous mixture of air and water vapor. how many phases are
Calculate of power [delivered heat/time] for adiabatic and two isothermal processes? Calculate of power [delivered heat/time] for this cycle which consists of two isobaric (constant pressure) and two isochoric (constant volume) processes?
two streams of air one at 1 bar 27degree and velocity of 30 ms and the other at 5 bar 227 degree and 50 ms velocity mix
During an experiment conducted in a room at 25°C, a laboratory assistant measures that a refrigerator that draws 2 kW of power has removed 30,000 kJ of heat from the refrigerated space, which is maintained at -30°C. The running time of the refrige..
R-134a enters the condenser of a refrigerator at 800kPa and 50oC at a rate of 0.018kg/s and leaves at 800kPa as a saturated liquid. It is known that the compressor consumes 1.2kW of electricity at this operating condition. Determine 1) heat rejection..
A coal-fired power plant produces and sells 10,000 MW electricity while operating at 40 % thermal efficiency. The sale price of electric power is $0.04 per kWh. How much power does it reject to the atmosphere? How much power (in the form of heat rate..
A piston-cylinder assembly contains air at 227C and 300 kPa. Heat is supplied from a reservoir at 900 K causing the air to expand the path Pv^1.2 constant until the pressure is 200 kPa. The surroundings are at 27C and 95 kPa. Determine the second law..
Draw a picture of the region of positive density D
