While washing up Grandma's old aluminum cooking pot I noticed that it would just barely touch the bottom of the sink if I added 2.5 cups of water to it. The pot is 3.5 in high and 9.5 in diameter. Thickness of aluminum is 3/16 in. With the 2.5 cups of water as cargo, it displaced 1.5 in of water in the sink.
a.) Determine the weight of the pot.
b.) Determine specific gravity if vol of the pot is 450mL with a std deviation of 38mL.
Water flows uniformly at a depth of y1 = 40 cm in the rectangular troweled concrete channel shown, which is 10 m wide and has a bed slope of So = 0.040 . What is the velocity in the channel before the hydraulic jump
A wastewater treatment plant has a flow of 35,000 m3/day. Calculate the mass of sludge wasted each day (QwXw, expressed in kg/day) for an activated-sludge system operated at a solids retention time (SRT) of 5 days
While the swing bridge is closing with a constant rotation of 0.5 rad/s, a man runs along the roadway such that when d = 10 ft he is running outward from the center at 5ft/s with an acceleration of 2 ft/s^2, both measured relative to the roadway.
How much must he set aside in his savings to account for the 3-months summer to cover his rent for next year. The savings account earns 3% with monthly compounding.
The traffic stream consists of cars, buses, and large trucks (no recreational vechicles). A weekday directional peak-hour volume of 1800 vehicles (familar users) is observed, with 700 arriving in the most congested 15 min period.
Maximum dry unit weight was found to be 114lb/ft^3 at a water content of 13.5% in labratory tests. Results of a field unit weight test were dry unit weight=111lb/ft^3 and a water content 11%.
suppose helen deposits $4000 today and one year from today she deposits $1000. Each year she increases her deposit by $500 until she makes her last deposits on roberta's 18 birthday. how much is on deposit after the 18th birhday
A soil sample with specific gravity of solids 2.70 has a mass specific gravity of 1.84 Assuming the soil to be perfectly dry,Determine the void ratio.
An aerosol with a lognormal size distribution has a count median diameter of 2.0 micron and a geometric standard deviation of 2.2. If the mass concentration is 1 mg/cubic meter what is the number concentration
A 45 W electric mixer is operated for 5 minutes while mixing a 2 kg shake. Assume Csubv=4200 J/kg-K for the liquid. Determine the temperature rise (in degrees C) of the milk shake.
The company can either buy a single 200m^3 ideal plug flow tank, or three 80m^3 completely mixed tanks that operate in series. the cost is essentially the same. The pollutant is removed as a part of a first order reaction with a rate constant value..
A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.
