A plastic bin with a volume of 1 gallon [gal] has a mass of 0.35 kilograms [kg] when empty and is sitting
on a table in a warehouse.
After the bin becomes partially filled, 1.3 pounds-force [lb] of force is applied to move the bin across the
table, and the bin and its contents accelerate at a rate of 1.5 meters per second squared Ignore
frictional losses.
Determine the total weight of the bin and its contents in units of newtons [N].
A cylindrical pipe with a cross-sectional radius r = 1.40[cm] is plunged into a l = 2.30[m] tall open water drum that is initially completely filled with water (pwater = 1000 [kg/m3]). The pipe goes h1 = 0.35 [m] above the drum before dropping down h2 = 3.50 [m] below the base of the drum as shown. The cross-sectional radius of the top side of the pipe is R = 2.20 [cm].A. How fast is the water going out of this pipe?B. What's the liquid's pressure at the top of the pipe? Assume that the system is exposed to 1.00 [atm] of air pressure.C. What's the maximum height the pipe can go above the drum before the water stops flowing out of the pipe? For liquid flow to be continuous, the liquid’s pressure must not fall before its vapor pressure. Assume that vapor pressure, in this case, is 2.30 [kPa].

During its fall, its initial potential energy is converted into kinetic energy. If the ball is dropped from a height of 680 centimeters [cm], and the impact velocity is 38 feet per second [ft/s], determine the value of gravity in units of meters per second squared [m/s2].arrow_forward
- NASA sent a probe to Saturn's moon Titan, where the acceleration due to gravity is 1.4 meters per second squared [ms2]. Titan's atmospheric pressure is 1.3 times Earth's atmospheric pressure at sea level. The probe landed in a lake of liquid methane, which has a density of 0.454 kilograms per liter [kgL]. Since the probe weighs 300 pounds-force [lbf] on Titan and has a volume of only 1.2 cubic feet [ft3], it immediately sank. It now sits 65 feet [ft] below the surface of the lake. The lake has a surface area exposed to the atmosphere of 24500 square meters [m2]. What is the total pressure exerted on the probe, in pascals [Pa]?arrow_forwardA robot is exploring Charon, the dwarf planet Pluto's largest moon. Gravity on Charon is 0.278 meters per second [m/s2]. During its investigations, the robot picks up a small spherical rock for inspection. The rock has a diameter of 6 centimeters [cm] and is lifted 16 centimeters [cm] above the surface. The specific gravity of the rock is 10.7. The mechanism lifting the rock is powered by a 9-volt [V] power supply and draws 1.09 milliamperes [mA] of current. It requires 13 seconds [s] to perform this lifting task. What is the efficiency of the robot?arrow_forwardIn a factory, 12 gallons [gal] of a liquid need to be raised 30 feet [ft] to be loaded into a piece of equipment. During this process, the electric motor loses 700 watts [W] to heat while operating in a circuit that requires 15 amperes [A] of current and 110 volts [V]. The liquid has a total mass of 5 slugs [slugs] and the mass of the container is negligible. Determine the time required to lift the liquid in seconds [s].arrow_forward
- A mixing chamber receives a steady flow of water from different parts of a processing plant. It has two inlets and one outlet. The mixing chamber is NOT well insulated and DOES allow heat transfer between the device and the surroundings. Kinetic and potential energy effects are negligible. Determine the mass flow rate at inlet 1 in [kg/s]. Determine the rate of heat transfer between the mixing chamber and the surroundings in [kW]; carefully indicate direction (i.e., does energy move by heat transfer to or from the chamber?)arrow_forwardA robotic rover on Mars finds a spherical rock with a diameter of 8 centimeters [cm]. The rover picks up the rock and lifts it 25 centimeters [cm] straight up. The rock has a specific gravity of 4.75. The gravitational acceleration on Mars is 3.7 meters per second squared [m/s²]. If the robot's lifting arm has an efficiency of 35% and required 10 seconds [s] to raise the rock 25 centimeters [cm], how much power in units of watts [W] did the arm use?arrow_forwardFor the following frame, determine the maximum shear force and bending moment, and the point where they occur.arrow_forward
