Refrigerant R-134a vapor in a piston-cylinder assembly undergoes a constant-pressure process from saturated vapor at 800 kPa to 50 ºC. For the refrigerant, determine the work and the heat transfer, per unit mass (each in kJ/kg). Changes in kinetic and potential energy are negligible.
System of force and cable tensions is in equilibrium and what are the necessary conditions for static equilibrium and determine the area moment of inertia about Ox for the area shown under the curve
Calculate the head provided by the pump and Calculate the brake power required if the pump efficiency is 75% (kW).
Evaluate the effect of the water spray on efficiency (net work out divided by heat input) and net power out per kg/s of dry air coming into the turbine.
Assume that viscous effects are negligible Plot this data using appropriate dimensionless groups

Geometric angle of attack, The Piper Cherokee has a wing area of 170 ft2 and a wing span of 32 ft. Its maximum gross weight is 2450 lbs. The wing uses a NACA 65-415 airfoil, which has a lift slope of 0.10331deg^-1 and alpha(L=0)= -3.0deg. Assume th..
Wind turbines are becoming more and more common as a method of energy production, wind turbines by their very nature are dynamic and are subject to and create their own internal and external kinematics and kinetics.
Derive eulers equation 1- Derive. From first principles eulers equation from the rate of change of momentum 2- Show by integration how Eulers equation derives Bernoullis equation
Effect of pressure on temperature and density of air for an adiabatic process, The pressure is to be raised from atmospheric to 7 psi (4.83 bar). The process is adiabatic, and the volume is constant and unknown.
The system on site is a pressure sand filter, with a service curve. The filter is backwashed using the feed pump, at a higher flow rate, shown as backwash curve. What is the speed of the pump to achieve the service and backwash flow rates ?
