Two gases X and Y having the same temperature T, the same pressure P and the same volume V are mixed. If the mixture has the volume V and temperature T, then the pressure of the mixture will be:
A 2kW electric resistance heater submerged in 5 kg water is turned on and kept on for 10 min. During the process 300 kJ of heat is lost from the water the temperature rise of water is.
The cutting force in punching and blanking operations mainly depends on
A concentrated load of P acts on a simply supported beam of span L at a distance from the left support. The bending moment at the point of application of the load is given by
A beam of length L is carrying a uniformly distributed load w per unit length. The flexural rigidity of the beams is EI. The reaction at the simple support at the right end is
Which of the following integration method can be used to find the deflection of a beam?
(of Bending Moment equation)
In a spring-mass system, the mass is 0.1 kg and the stiffness of the spring is 1 kN/m. By introducing a damper, the frequency of oscillation is found to be 90% of the original value. What is the damping coefficient of the damper?
A vehicle suspension system consists of a spring and a damper. The stiffness of the spring is 3.6 kN/m and the damping constant of the damper is 400 Ns/m. If the mass is 50 kg, then the damping factor (D) and damped natural frequency (fn), respectively, are
A flat plate collector is 150 cm wide and 180 cm high and is oriented such that it is perpendicular to the sun rays. Its active are is 90% of the panel size. If it is in a location that receives solar insolation of 1000 W/m2 peak, the peak power delivered to the area of the collector will be
In solar flat-plate collectors, the absorber plate is painted with selective paints. The selectivity is the ratio of
