998.8 lbs.
About 9171 pounds if the water is at 4C, a little less if the water is hot. You did not give the weight of the empty spa so you would have to add that to the weight of the water provided.
About 8,040 liters.
About 235 pounds. To figure that, find the volume of the pool in gallons (pi X radius squared X height) and multiply the answer by the approximate weight of a gallon of water (8.3 pounds). Hope that helps.
THE GALLONS have NO Bearing on the pressure it would have to do with the HEIGHT and then if you wanted to know the WEIGHT you would take the 1,500 gallon and times it by 8.33
The weight of the block at the time of the drop would ensure that the block goes into the water pretty deep depending on the size and weight of the block. After going into the water in the first instance, it would then float.
142794 Pounds if it is 4 ft deep 107230 if it is 3 ft deep.
water has a density of 62.4 pounds per cu ft and tank is 36 cu ft 62.4 x 36 = 2246 pounds
No. Your mass would be the same wherever you are. You weight might be a little different between being in a deep mine and a mountain top. Although both weight and mass are measured in pounds or grams, weight is the effect of gravity on your mass.
They do not dive deep enough.
A object weighing 10 pounds with a volume of 1 cubic foot will sink until 0.16 of its volume is under water, and the remaining 0.84 of its volume is above the surface. At that point, the weight of the displaced water is (0.16 cubic foot) x (62.5 pounds/cubic foot) = 10 pounds, and the object will float at that depth, and sink no further.
A one by one by two meter tub has a volume of 2 square meters or 70.63 cubic feet. Such a volume will contain 528.3 gallons of water. At 8.345 pounds per gallon, the water in the tub will weigh 4409 pounds.
Well, if you can imagaine that weight of 1,600 elephants on every square cm of your body. That's the pressure on your body.
