An electric motor consumes 9.00 KJ of electrical energy in 1.00 min. If one third of this energy goes into heat and other forms of internal energy of the motor, with the rest going to the motor output, how much angular speed is required to run this motor when 0.382 Nm torque is applied.
the compression stages in the axial compressor of the industrial gas turbine are close coupled making intercooling very
a particle travels along the circular path x2 y2 r2. if the y component of the particles velocity is vy 2r cos 2t
In a dairy plant, milk at 4°C is pasteurized continuously at 72°C at a rate of 12 L/s for 24 h a day and 365 days a year. The milk is heated to the pasteurizing temperature by hot water heated in a natural-gas-fired boiler that has an efficiency o..
assuming that steam can be treated as an ideal gas what would the specific volume of steam be at 600deg f and 120 psia
A particle which movies in a two-dimensional curvilinear motion has coordinates in millimetres which vary with time t in seconds according to x=5t2 +4 and y=2t3 + 6. For time t =3s, determine the radius of curvature of the particle path and the magni..
A regenerative steam power cycle has a closed feed water heater that heats 20 kg/s of water from 100°C, 20 MPa to 250°C, 20 MPa. The extraction steam from the turbine enters the heater at 4 MPa, 275°C, and leaves as saturated liquid. What is the req..
five kilograms of saturated vapor water at 1 mpa is contained in a cylinder fitted with a movable piston. this system
Steam flows at steady state through a well-insulated pressure-reducing valve. At the inlet, the pressure is 4 MPa, the temperature is 320°C, and the velocity is 60 m/s. The pressure of the steam at the exit is 700 kPa.
the particle a is mounted on a light rod pivoted at o and therefore is constrained to move in a circular arc of radius
a commuter train traveling at 40 mi h is 3 mi from a station. the train then decelerates so that its speed is 20 mi h
in an accelerator protons emerge with velocity of 2.5 x 108 ms. the accelerator is 0.8km long.a if the acceleration is
During a test of a metal bar, it was found that a axial tensile force of 10,000 lbs resulted in an elongation of 0.023 in. The bar had these original dimensions, length 10 in. diameter 0.750 in. Compute the modulus of elasticity of the metal. What ki..
