Task 1.3 to Determine water density with a pressure r=3,6mpa if with a pressure of 0,1 MPas density of water of 1000 kg/m3.
Task 2.3 to Define the indication of the manometer if absolute pressure on a free surface of a tube r0=0,07mpa, liquid level in tube N=4m, and liquid level in h=2,5m tank.
The task 3.3 Copper of system of water heating has a manhole for survey by diameter of D=1m. The manhole is closed by the flat cover attached by n=20 bolts. Water level is in a broad tank at height N=20m, and the cover center of gravity at h=2m height from the axial line of a copper. To determine the necessary diameter of bolts.
The task 4.3 Water diameter of d=1m follows from a pipe in a tray width of b=2m and depth of h=0,5m liquid. During t=50c on cross sections there passes the mass of water M=50t. To determine water speeds in a pipe and a tray, and equivalent diameters of a pipe and a tray.
The task 5.3 Kerosene, density ρ=750 on the self-flowing pipeline diameter of d=80mm flows from the right tank in Q=17l/page, left with an expense. Pressure in tanks of pm1=0,17mpa, pm2=0,26mpa. Losses of a pressure in the pipeline pay off on a formula h1-2 = 30V2/2g where V – speed in a pipe. To calculate a difference of levels of kerosene in H tanks.
The task 6.3 Water in number of Q=25l / with proceeds on a horizontal pipe. To define loss of a pressure on sharp expansion of a pipe from diameter of d1=150mm to d2=200mm.
The task 7.3 Pump transports water l=120m length, diameter of d and a roughness of a surface of a pipe k=0,2mm with a mass expense of Qm=1kg/page. Liquid level is in a tank at height N=8m, coefficient of local resistance ζм =2,5. Indication of the mercury hrt manometer =300mm, and pm=0,15mpa manometer. To calculate diameter of the pipeline d.
