A closed rectangular tank 1.2 m high, 2.4 m long and 1.5 m wide is two-thirds full of gasoline (specic gravity 0.8). Calculate the acceleration which may be imparted to the tank so that the bottom front end of the tank is just exposed. Also calculate the total forces on each end of the tank and show that the dierence between these forces equals the unbalanced force necessary to accelerate the liquid mass in the tank.

A rectangular tank 1.5 m wide, 3 m long and 1.8 m deep contains water to a depth of 1.2 m. Find the horizontal acceleration that may be imparted to the tank in the direction of its length so that 1. the water is just about to spill 2. the front bottom corner of the tank is just exposed. 3. the bottom of the tank is exposed to its midpoint. For (2) and (3) above, compute the volume of the...

A 2-m-high, 4-m-wide rectangular advertisement panel is attached to a 4-m-wide, 0.15 m-high rectangular concrete block (density = 2300 kg/m3) by two 5-cm-diameter, 4-m-high (exposed part) poles, as shown in the figure. If the sign is to withstand 150 km/h winds from any direction, determine (a) the maximum drag force on the panel, (b) the drag force acting on the poles, and (c) the minimum length L of the concrete block for the panel to resist the winds. Take the...

An 800-gallon, 1.2 m wide cylindrical water tank is filled to the brim. The tank has a hole formed at 13.3 cm above the ground. It is observed that water leaks out of the reservoir at a speed that reduces by 3.2 m.s-1 in 1 minute 39 seconds. If the tank was initially filled to the brim how much water leaked out of the tank, and 8.2 by how much shall the point, at which water lands, change? (1 gallon...

A rectangular car tank 20m long, 4m wide and 3m deep is completely open at the top. If it is initially filled to the top: (a) How much liquid will be spilled if it is given a horizontal acceleration of 0.3g in the direction of its length? (b) What is the maximum hydrostatic force acting on the side opposite the direction of the acceleration. (c) Determine the volume of the remaining water at the tank.

A relativistic rocket is measured to be 52 m long, 2.4 m high, and 2.1 m wide by its pilot. It is traveling at 0.65 c (in the direction parallel to its length) relative to an inertial observer. B) What is the length of the rocket as measured by the inertial observer? C) What is the volume of the rocket according to the pilot? D) What about the inertial observer? E) If the rocket and pilot combined has a mass...

Two parallel rectangles having emissivities of 0.6 and 0.9 are each 1.2 meters wide and 2.4 meters high. They are positioned 0.6 meters apart. The plate with ? = 0.6 is at 1000 K while the other is 420 K. The surroundings are at 290 K and may be assumed to absorb all energy that escapes the two plates. (a) What is the total energy lost (Watts) from the hotter plate (radiosity)? (b) What is the radiant energy exchange (Watts)...

A retaining wall against a mud slide is to be constructed by placing 1.2 m-high rectangular concrete blocks (ρconcrete = 2700 kg/m3 ) side by side, as shown in Figure 1. The friction coefficient between the ground and the concrete blocks is f = 0.3, and the density of the mud is about 1800 kg/m3 . There is concern that the concrete blocks may slide or tip over the lower left edge as the mud level rises. a) Determine the...

A rectangular, well-mixed aeration lagoon is 75 m long, 5 m wide, and 2 m deep. It receives 400 m3/d of wastewater with a BOD5 of 367mg BOD5/L for treatment. The biodegradation rate constants for the wastewater are the following: yield coefficient = 0.8 mg VSS/mg BOD5, endogenous decay constant = 0.08 d-1, maximum specific microbial growth rate = 1 d-1, and half velocity constant = 76.0 mg BOD5/L. What must the hydraulic detention time be in the aeration...
