Answer:

 The planer four bar linkage is the type of closed chain linkage and it is also simple movable linkage system. It is also known as "four-bar" linkage.

In this type of four bar linkage the re-volute joints are mainly designed to handle the transverse load easily as compared to load acting on the length of the link.

The planer four bar linkage are mainly constructed when the four types of links are mainly constructed in the loop format by using the joints. These joints are basically configure so that the links can easily move in the parallel plane system.

A series circuit has 4 identical lamps. The potential difference of the energy source is 60V. The total resistance of the lamps
Alexxx [7]

Answer:

I=3A

Explanation:

From the question we are told that:

Number of lamps N=4

Potential difference V=60v

Total Resistance of the lamp is R= 20ohms

Generally the equation for Current I is mathematically given by

 I=\frac{V}{R}

 I=\frac{60}{20}

 I=3A

The minimum fresh air requirement of a residential building is specified to be 0.35 air changes per hour (ASHRAE, Standard 62, 1
Thepotemich [5.8K]

Answer:

a) The flow capacity of the fan is 3150 L/min

d) the minimum diameter is 0.11 m

Explanation:

given data:

A = area of residence = 200 m²

h = height of building = 2.7 m

Percentage of air that must be replaced by fresh air is 35%

v = velocity of air in the duct = 5.5 m/s

a) The volume of the entire building is:

Volume=2.7*200=540m^{3}

The flow capacity of the fan is equal to:

Flow=\frac{0.35*540}{60} =3.15m^{3} /min

Flow=3.15\frac{m^{3} }{min} *\frac{1000L}{1m^{3}  } =3150L/min

b) The volume flow rate of fresh air is equal to:

Flow=\frac{\pi *d^{2} }{4} V\\d=\sqrt{\frac{4*Flow}{\pi V} } =\sqrt{\frac{4*3.15}{\pi *5.5*60} } =0.11m
