When analyzed, the samples were found to have quite similar characteristics. These findings convinced many that a method of study was needed. The study of oceans was named oceanography. Density, salinity, and temperature are very important concepts in the study of oceanography. The salinity and temperature of the water influence its density, and the differences in density are the major factor in understanding the formation of currents and the positions of water masses in the sea.
For the first procedure, we increased the frequency until we found resonance, and recorded frequencies and nodes to calculate wavelength. We did this for first harmonic through fourth harmonic, and then found the velocities using our measurements. In the first harmonic phase, our signal generated frequency was 36±1 Hz, wire frequency was 72 Hz, the number of nodes was 2 and the wavelength was 1.200 m. This was found by using the equation λ=2L/n. For the second procedure, using a wire of a certain linear mass density we found the frequency of the wire as it oscillated in its fundamental mode, or lowest resonance mode, as we increased the tension by moving the hanging mass to a higher notch. We performed this procedure again using a wire with a different linear mass
Using this information, we can calculate the amount of the block that should be underwater using the following, mblackg=Fbouyancy=mdisplaced waterg therefore, ρblockVblock=ρwaterVdisplaced water →ρblockh=ρwaterx. Experimental Overview The purpose of this lab is to measure volumes and masses to compute density, and measure displaced volumes and buoyancy forces. First, we measured the radius of the
The difference is the buoyant force FB=Wout – Win. Finally we calculate percent error between the theoretical and experimental value for each shape: % error=(Measured – Theoretical)/Theoretical x 100%. In the next part of the lab, we compare the predicted and the measured capacity of a tuna can boat. The predicted capacity is calculated to be 0.183kg, and then we load the boat until it sinks and subtract 0.001kg to get the measured capacity. Finally, we analyze the errors in both parts of the lab by propagation by substitution and compare the theoretical-experimental values using errors.
Form this concern, a non-linear model is proposed by Lupoi et al (2007) that allows accounting for wave-structure-soil interaction and evaluate the dynamic response of caisson breakwater subjected to impulsive wave loads, but is also fast and accurate enough to be used in design of caisson breakwaters. The caisson (figure- 3) is represented by a rigid block sitting on a mattress of non-linear springs. The caisson transfers horizontal and vertical forces to the foundation soil when a wave hits the superstructure. The structure is modeled as a 3-DOF, two translation and one rotation. The dynamic properties of the system include contributions by the superstructure, water surrounding the structure and the soil
Find the total force due to the water on the slide of the pool which is 20 meters long and 10 meters wide if the water is at a uniform depth of 1.2 meters. Given: H = 12m W = 10m L= 20m Find: FTota=? Solve for Area: A= LxW A=20mx10m A=200m2 Solve for Pgauge: Pgauge= ᵨgh Pgauge= 1000kg/m2 (9.8m/s2)(1.2m) Pgauge = 1170 Pa Solve for Fgauge: P= F/A Fgauge= PAgauge Fgauge= 11760 Pa (200m2) Fgauge= 2,352,000 N Convert bar to Pa: Patm = 1.013 bar x 〖10〗^5/(1 bar) Patm = 101,300 Pa
Merit Task Produce clear and accurate answers to three different calculations across the range of Human Comfort Factors. 1. Thermal calculations Here I will calculate the amount of heat loss through 150m² of cavity wall. The difference in temperature between inside and outside is 14ºC In order to find out the total heat loss I will need to calculate the ‘U-value’ of the wall, which is the rate of heat loss through 1m² of element for each ºC. Below is a table showing the elements that make up the wall.
Firstly, understand the chart datum. Bear in mind that all tides will be measured against the define plane of reference, called the Chart Datum. Chart Datum is an essential reading of tide which state the average of low tide heights. It is also can be used to measure the depth of the sea. If the height of the tide is calculated in a specific location, and added to the chart datum, one can determine the true depth of water at a specific time.
Main span of tower bridge is 60.96 m. Side spans are 82.3 m. HEIGHT OF DECK: The two side spans, each 270 feet long, are of the suspension type. The central span has two high-level foot ways side by side, and one low-level roadway. High-level girders carry the upper footways, which are reached by hydraulic lifts or staircases in the main towers. The roadway, or central opening span, is 200 feet long and consists of two bascules or leaves. The Tower Bridge Act laid down that when the bridge was open there should be a clear headway at high tide between the water and the high-level footways of 135 feet and a headway of 29 feet when the bridge was closed.
