In constructing dams, the concrete is poured in lifts of approximately 1.5 m (y1 = 1.5 m). The forms for theface of the dam are reused from one lift to the next. The figure shows one such form, which is bolted tothe already cured concrete. For the new pour, what moment will occur at the base of the form per meter oflength (normal to the page)? Assume that concrete acts as a liquid when it is first poured and has a specific weight of 24 kN/m3.
In the branched pipe system shown in Fig. 12.8, 850 L/min of water at 10°C is flowing in a DN 100 Schedule 40 pipe at A. The flow splits into two DN 50 Schedule 40 pipes as shown and then rejoins at B.
Three return steam lines in a chemical processing plan enter a collection tank operating at a steady state at 1 bar. Steam enters inlet 1 with flow rate of 0.8 kg/s and a quality of 0.9. Steam enters inlet 2 with flow rate of 2kg/s at 200 degrees C. ..
the velocity of point p relative to frame a is vpa -14.9 i 19.4 j fts and the acceleration of p relative to frame b
find (a) the power rating of the electric heater and (b) the temperature rise that the air experiences each time it passes through the heater.
Volumetric Compression Ration and Mean Effective Pressure of a Diesel Engine, A diesel engine has air before compression at 280 K and 85 Kpa. The highest temperature is 2219 K and the highest pressure is 6 MPa.
What are the natural frequencies of the system?
The distance from the centre of rotation to the centre of the mass is 1.5 m and the diameter of the wire is 2 mm. If the ultimate tensile strength of the steel is 500 MPa, determine the rotational speed at which the wire will break.
a carnot refrigerator consuming 3.0 kw is located in a room where the air temperature is 25degc. the coefficient of
If the density of the water is 62.4 lb/ft3, what is the mass of water stored in the tower, in lb, when the tank is full? What is the weight, in lbf, of the water if the local acceleration of gravity is 32.1 ft/s2?
A 15-tooth pinion cut with a 10-pitch, 25° hob drives a 45-tooth gear. Using a computer, calculate the backlash produced when the center distance is increased twin 3.000 in. to 3.030 in. by increments of 0.0010 in.
The mass of a spring-mass system vibrates on a dry surface inclined at 30° to the horizontal as shown in Fig. 2.116.
