answer the following given questions in detail
A piston-cylinder device initially contains 50 L of liquid water at 40°C and 200 kPa. Heat is transferred to the water at constant pressure until the entire liquid is vaporized.
(a) What is the mass of the water?
(b) What is the final temperature?
(c) Determine the total enthalpy change.
(d) Show the process on a T-v diagram with respect to saturation lines.
water from a treatment plant is pumped into distribution system at a rate of 4.38 m^3/sec, a pressure of 480 kpa and a temperature of 20 degree celcius. The pipe has a diameter of 750 mm and is made of ductile iron
A three span continuous beam has spans of 27, 30, and 27 feet. The beams support one-way slabs, 6 inches thick that span 20 feet center to center. Assume that the beams are 16 inches wide and 24 inches deep.
The problem belongs to Civil Engineering and it is explain about a building which is constructed with the method of dropping fossil fuel consumption and to reduce the carbon footprint of the building.
Draw the shear and moment Diagram for a beam that is 10 feet long, supported on the left end by a roler, and the right end by a pin, and has a 1000 lb load placed in the center i.e at 5 feet.
Compute the critical buckling load for a 2.5m timber column of full size square section 0.10m x 0.10m. The column has pinned ends(k=1). Assume the modulus of elasticity is 12Gpa and that the Euler formula applies.
An experiment was conducted to determine the hydraulic conductivity of an artesian aquifer. The piezometric heads at two points 150m apart were found to be 55 m and 48.5 m above a datum.
It has been estimated that the emission of NOx from a coal fired power plant is 1300 g/s. At 100 km downwind (y=10m), what is the concentration of NOx in g/m^3. The wind speed at the top of the stack with a height of 100m is 6.5 m/s and an inversion ..
An insurance sales representative sells policies to 5 men, all of identical age and in good health. According to the actuarial tables, the probability that a man of this particular age will be alive 30 years hence is 2/3. Find the probability that in..
