Steam enters the adiabatic turbine at a temperature of 500C, a pressure of 10 MPa and exits at a pressure of

8 MPa. Determine the work product per unit mass of steam if the process can be reversed.

One kg of air at 40oC dry bulb temperature and 50% relative humidity is mixed with 2 kg of air at 20oC dry bulb temperature and 20oC dew point temperature. Calculate the dry bulb temperature and specific humidity of the mixture. What is the relative humidity and dew point temperature of the mixture?

in the turbine of a gas turbine unit, the gases flow through the turbine at v17 kg/s and the power developedb by the turbine is 14000 kW

What does M stands for in the calculation of deflection of beams.

If the volume of the room is 15 m3, what ventilation rate in ACH must be maintained to keep radon levels below the US EPA recommended limit of 4 pCi/liter? What is the primary sink for radon in the cellar?

A root cellar receives an input of 0.1µCi of radon-222 per hour through the dirt floor. Radon-222 has an approximate half-life of 3.8 days.

Calculate Machine Cutting Time (show all work) A person cuts a piece of Bronze that is 4" long with a 2" Dia., down to 1.600 Dia. It is done in 3 passes. (2 roughing and 1 finishing pass) Length Time = Rate Rpm Length = Length of cut Rate = Feed x Rpm CS x 4 D Pass 3 = 1.610 to 1.600 dia. Pass 1 = 2" to 1.800 dia. Pass 2 = 1.800 to 1.610 dia. CS = 90 for roughing and 100 for finishing. Feed = .015 - .025 roughing and .003 - .010 finishing Length = 4" What is the machine cutting time in seconds)?

One kiliogram of steam expands isentropically from 2.0 MPa and 360°C to 90°C. find the final quality and the work for non-flow and steady flow process.
