Answer:
Between 35°– 45°
Explanation:
In the vertical position, Point the flame in the direction of travel. Keep the flame tip at the correct height above the base metal. An angle of 35°–45° should be maintained between the torch tip and the base metal. This angle may be varied up or down to heat or cool the weld pool if it is too narrow or too wide
Answer:
This is self locking.
Explanation:
Given that
Diameter d= 40 mm
Pitch (P)= 6 mm
Torque T= 1 KN.m
Friction(μ) = 0.1
Thread is double square.
Condition for self locking
L= n x P
N= number of start
Here given that double start so n=2
L=2 x 6 = 12 mm
(μ = 0.1)
So from we can that this is self locking.
Answer:
water released through the bottom of the reservoir in 24 hrs is 1992 ha-cm
Explanation:
Given the data in the question;
A = 200 hectare = 2 × 10⁶ m²
water evaporated Ve = 2 × 10⁶ m² × 3 × 10⁻² = 60000 m³ { in 24 hrs }
Water added by storm in 24hrs Vi = 3 × 24 × 3600 = 259200 m³
now let water released be Vr
ΔV = V_ini - V_final = 0
Vi - Ve - Vr = 0
Vr = Vi - Ve
Vr = 259200 m³ - 60000 m³
Vr = 199200 m³ = 19920000 m² - cm
Vr = 1992 ha-cm
Therefore, water released through the bottom of the reservoir in 24 hrs is 1992 ha-cm
