Answer:
c) It takes a greater hydraulic head to drive the groundwater laterally to the well casing in the lower permeability aquifer
Explanation:
The groundwater are contains under the rock and in the open spaces within the rocks and the unconsolidated sediments. Aquifer refers to the underground layers of the permeable sand or rocks that transmits the groundwater below water table which provides a sufficient supply of water to the well. Groundwater is present everywhere where there is porosity in the rocks and it depends on the permeability of the rocks to allow them flow.
A drawdown cone is completed in the lower permeable aquifer deeper and narrower than the high permeable aquifer as it takes more amount hydraulic head or energy to drive groundwater to the well casing which is in the lower permeable aquifer.

Answer:
the lost work per kilogram of water for this everyday household happening = 0.413 kJ/kg
Explanation:
Given that:
Initial Temperature
= 15°C
Initial Pressure
= 5 atm
Final Pressure
= 1 atm
Data obtain from steam tables of saturated water at 15°C are as follows:
Specific volume v = 1.001 cm³/gm
The change in temperature = 2°C
Specific heat of water = 4.19 J/gm.K
volume expansivity β = 1.5 × 10⁻⁴ K⁻¹
The expression to determine the change in temperature can be given as :


Δ T = 0.093 K
Now; we can calculate the lost work bt the formula:

where ;
is the temperature of the surrounding. = 20°C = (20+273.15)K = 293.15 K
From above the change in entropy is:






Thus, the lost work per kilogram of water for this everyday household happening = 0.413 kJ/kg
Answer:
1 pulse rotate = 9 degree
Explanation:
given data
incremental encoder rotating = 15 rpm
wheel holes = 40
solution
we get here first 1 revolution time
as 15 revolution take = 60 second
so 1 revolution take =
1 revolution take = 4 seconds
and
40 pulse are there for 1 revolution
40 pulse for 360 degree
so 1 pulse rotate is = 
1 pulse rotate = 9 degree
Answer:
Conductor
Explanation:
Current is carried by a conductor.
__
The purpose of a dielectric and/or insulator is to prevent current flow. An electrostatic field may set up the conditions for current flow, but it carries no current itself.
